I have some difficulties in modelling LiBr/H2O absorption cooling system in Transient state. Any help, guidelines, or advice?

How two melting peaks in DSC of polypropylene can be merged into one crystallization peak?

The figure shows DSC cooling (blue) and 2nd heating (green) curves (step: 10 K/min) for a commercial sample supplied as Atactic Polypropylene (APP). The heating curve illustrates two major...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

I have also used EES for this purpose, Frankly speaking, for LiBr-H2O system transient analysis is quite difficult. First go for steady state modelling. There is a lake of resources available for transient state analysis. So go for steady state analysis.

Juan Pablo Vargas Bautista

I suggest you to search for dynamic simulation that deal with the start up operation of the absorption chiller, may be these articles can help you with your mathematical model to introduce them to EES.

A simple way is to simulate many steady state conditions, and after you can take them as oututs and using another program for a quasi steady analysis. The otehr program can be a small code in matlab or fortarn. Moreover, if you have TRNSYS, you can couple EES and TRSNYS...
