EES is one the most best options we have.

But I also recommend ASPEN PLUS. It seems to be more powerful than EES.

In EES you will write codes for modelling a cycle, like MATLAB. But in ASPEN you can select components from software's directory and work on them.

Of course learning how to work with EES is much easier. You are basically writing thermodynamic equations.

Thank you for your guide Heather E Dillon

how about Thermoflow ? have you ever analyzed a cycle with thermoflow?

i would be so grateful to read your experience about it

Dear Amirhossein

As Heather commented, EES is a good software to solve thermodynamics problems. You can fined and learn working with it easilly. If you want to work with a user friendly software and dont like to write codes, Thermoflow and Cycle Tempo are two useful devices. In Tehran you can join PTEC training company to learn how to work with them.

Regards

Dear Amirhossein,

As Dr. G. Ahmadi says, 'EES' Could help you. Using this software you will be a profesional cycle designer in your way. EES is a unique and very professional tool for any energy system modeling.

Best.

dear friends Abdollah Mehrpanahi , Gholamreza Ahmadi

thank you for your help

best regards

Dear Amirhossein,

I recommend you to use MATLAB in conjunction with REFPROP property data. This will help you in doing optimization studies in future.

Kind Regards

Matlab can be used, For my research work, I used this software for energy and exergy analyses of power plant system.

Thank you dear friends for the answers T Ashok Kumar Sahand Saeidi Abubakr Ayub

For components like energy storage, solar collectors, pv, etc. TRNSYS is a good option. Besides, it can be coupled with EES or Matlab.

I have used Thermoflow tools and Aspen Plus. I haven't seen solar functions in Aspen, but I was using it for a very different study. The Thermoflow Thermoflex product is very good but may not include all the solar functions you are looking for either. I have seen that the product is upgraded regularly and often includes new model functions. I recommend that you check with Thermoflow - they are pretty responsive.

Paul Willson Eduardo Ruiz-Casanova thank you , i found your answers so helpful

Ebsilon IS OK

I agree with Paul Willson, the Thermoflex product of Thermoflow is very useful but if you need all the components that you say, the full Thermoflow package is more recommendable (but more expensive too).

You can check Cycle Tempo.

EES is Ok but if you want to optimize the system using genetic algorithms or other conventional techniques you should use Matlab+Refprop.

EES undoubtably one of the most powerfull one in this topic

EES is one of the best, but you will have to write the equations

I recommend TRNSYS for solar components, while EES and MATLAB for modeling of other systems.

Hi,

There are a lot of software that you can use to model your mentioned type of projects such as Aspen Plus, Hysys, Transys, thermoflow, and EES.

In EES you have to write the formulation which sometimes is time consuming.

Modules and extensions of Thermoflow is hard to achieve.

Aspen Plus and Hysys are more popular among chemical engineers and energy

professionals compromising you to find somebody in your region to help you in trouble shooting.

Best Wishes

For analysis of solar thermal cycles TRNSYS is best software to retain real time simulation.

Dr. D.B. Jani

EES,ASPEN+

EO modeling in Matlab by using Coolprop would be appropriated. You could even link them to ASPEN plus via Excel VBA

EES is the best but thermoflow is useful program for thermodynamic cycle.

When you know the governing equations of the components, EES is one of the best thermodynamic analysis tools

EES is a nice and practical software but in my opinion, aspen plus is more user-friendly

Hi

With Cycle-Tempo, you can design, analyze, optimize and monitor the thermodynamics of the energy system that you design and operate. Special features include:

• Extensive and validated model library that includes conventional, but above all, innovative systems and components (fuel cells, IGCC, CO2 capture plants, ORC turbogenerators, refrigeration absorption systems, etc).
• Ready-made models of components and even of complete energy conversion systems, so that you can tailor them to your special needs, shortening the model development time.
• Full-featured exergy analysis for the correct optimization of the design and operation of your system.
• Possibility of real-time integration with existing plant-wide data monitoring systems for performance analysis and trouble-shooting.
• Robust and efficient solver for large non-linear algebraic systems of equations, tailored to the special case of mass and energy balances. Our solver proved itself on the most demanding problems.

You may also consider Ebsilon Professional. It should have all components you need. Not sure it does energy analysis though. Aspen Plus would be a good choice too but you would need to write your codes for solar and energy storage components. As it's been said above, if you've got all governing equations at hand, EES is a good option.

I recommend you EES and HYSIS.

You can used the EES (Engineering equitation solver) program, its easy and suitable for all thermodynamic process

EES

TRNSYS

EES, TRNSYS & Maybe COMSOL Multiphysics

TRNSYS and FORTRAN to write your own model

Mr. Bilal Lamrani

dear sir,

the Fortran program haven't a properties of the fluid u must be write a table and edit it. but the EES program having many properties of fluids.

thanks

EES is one the best tools, however it is a software which solves system of equations and you must write the governing equations by yourself.

Thank you Mohammad Vajdi sir for your valuable reply.

The most popular sites are:

EES and HYSIS.

Emad

Thank you respected Emad Kamil Hussein sir for your valuable reply.

Dr. D.B. Jani

If you are interested in formulating your governing equations and writing your own code, then EES is a very good environment that allows for that in addition to parametric and optimization studies, especially when coupled with MATLAB.

If you are interested in using mainly predefined components without worrying about numerical solution details of the governing equations, then I recommend IPSEpro 7.0. It has extensive libraries for most fields in energy and chemical engineering (e.g., biomass, CSP, vapor cycles, gas cycles, refrigeration cycles, TES, etc.).

I prefer IPSEpro over other options such as ASPEN Plus, Cycle-Tempo, ASPEN HYSYS, TRNSYS, and Thermoflex because of its more comprehensive nature. In other words, if you are interested in a polygeneration system of any sorts, IPSEpro is the best option in my opinion (Thermoflex also has very similar capabilities). If you are interested in more specialized processes, then other software may provide more detailed models and more in-depth analysis (e.g., ASPEN Plus for thermochemical processes).

Thank you Omar Z. Sharaf sir for your valuable reply.

Dr. D.B. Jani

The starting point of thermodynamic logic is: 1) opposing perpetual motion. 2) The irreversibility of dynamics. Let's look at how to get Carnot efficiency = 1-T1/T2.

1.1 There are many kinds of type 2 perpetual motors, each of which is a natural phenomenon.

A) Machine A: against the irreversibility of thermodynamics (diffusion, heat conduction, friction, etc) - dynamics;

B) Machine B: Utilizing the Difference of Carnot Efficiency (Reversible Thermodynamics) - Thermodynamics

1.2 A and B belong to different disciplines. There is a parallel relationship between them and there is no logical mutual inevitability.

1.3. Logic of the Second Law of Thermodynamics:

Experience induction, deny that A machine==> B machine can not be manufactured==> All material Kano efficiency: 1-T1/T2.

1.4 The logic of the second law of thermodynamics violates the physical logic that A and B cannot be inferred from each other.

1.5 The second law of thermodynamics elevates the "irreversibility", which is in fact only a kinetic experience.

📷 Detailed discussion can be found in the following figure.

1. The second law of thermodynamics loses the ability of quantitative prediction.

2. Data processing method of law 2 of thermodynamics violates scientific discipline: modifying experimental data to satisfy theory

See the picture for details.

3. The second law of thermodynamics can only be called science if it reaches the same quantitative prediction ability as Newton's second law, otherwise it is pseudoscience.

4.Unfortunately, all the charts of enthalpy and entropy are organized in this way.

Comparison of New and Old Thermodynamics

1. Logic of the Second Law of Thermodynamics: Subjectivism, Logical Jump, Interdisciplinary Argumentation.

2. New thermodynamics pursues universality, two theoretical cornerstones:

2.1 Boltzmann formula: ro=A*exp(-Mgh/RT) - Isotope centrifugal separation experiments show that it is suitable for gases and liquids.

2.2. Hydrostatic equilibrium: applicable to gases and liquids.

3. The second and third sonic virial coefficients of R143a derived from the new thermodynamics are in agreement with the experimental results.

3.1. The third velocity Virial coefficient derived is in agreement with the experimental data, which shows that the theory is still correct when the critical density is reached.

4. See Appendix Pictures and Documents for details.

EESis the best software

1， The second law of thermodynamics is incorrect. See figure below for details.

2，The system is isothermal and exchanges heat with a large heat source to keep the temperature constant. Only volume changes are discussed.

3，The problem here is that the actual system is balanced and the second law of thermodynamics judges it to be unbalanced.

Programing in MATLAB or TRNSYS

A would recomended Ebsilon from Germany

I would recommend using CoolProp, an open source thermo-physical property library, coupled with Python or other programming language. CoolProp, written in C++, has full-feature wrappers for Python (2.x, 3.x) ,C++, Modelica, Octave, C#, VB.net, MathCAD, Java, Android, MATLAB and high-level interface for Labview, EES, Microsoft Excel, LibreOffice, Javascript, PHP, FORTRAN, Maple, Mathematica, Scilab, Delphi & Lazarus, Julia [http://www.coolprop.org]. See the original paper here [Article Pure and Pseudo-pure Fluid Thermophysical Property Evaluatio...

We have used this approach, i.e. using CoolProp, coupled with Python, for our research work on thermodynamic evaluation of cascade refrigeration cycle and MSW-fired power plant and found it to be user-friendly.

A user-friendly open source software/modeling framework capable of seamlessly analyzing thermodynamic cycles would be invaluable for teaching and research in developing countries as the academic institutions here are often unable to purchase the commercial software due to budget constraints. CoolProp, coupled with Python, could be that alternative.

Dear Amirhossein Eisapour ,

ASPEN Plus, EES (good environment)and DigSilent is best you can use.

I would prefer to go ahead with ASPEN PLUS.
