ich  kann nur die kreuzchen setzen in Comsol5.2, verstehen tue ich da nicht viel.

aber ich lerne gern mehr. bis jetzt habe ich ohne magnet Feld simuliert. Es gibt vieles was ich noch icht kann mit dem Comsol. Aber man kann sich helfen lassen im Comsol Forum (manchmal). Habe nur 16GB zu verfügung, was nicht reicht für 3D.

Schöne Grüsse aus Esslingen

Hi Johannes, I am very much intrested in FEA tools, my hands on static simulations, I have not done any thermal/Plasma simulations..let me try

B'r

Asit

Thanks for the nice resonance so far - I forgot to add that the simulations will have to deal with a fluid in motion, so not just a resting volume of gas.

Hi Markus,

thanks for the hint - about the optimised geometry I want to wait until I hear something from my submitted manuscript because based on the referees comments there might be changes there.

From my previous works it came out the rf or microwave plasma is the most suitable. As the reactor uses CO2 dissociation the mixture in steady-state operation will be CO2, O2 and CO mainly (most likely also O and C atoms/ions) but this should already yield quite some reaction channels in the plasma.

Am INP bist du doch bestens umgeben.. Habt Ihr keinen Studenten mehr?

Hello Johannes,

what are the dimensionality and the size of the system?

FG, David

Hi David,

nice to hear from you - how are you these days? I hope well and fine :)

The size of the system is in the order of meters (0.1 ... 2.0 m) depending on the amount of oxygen that should be produced in a certain time (for starters I would take 0.5 m x 0.5 m x 1.0 m), which is already quite large, the pressure is around 7.5 mbar.

A 2D simulation would already be awesome but for first runs also 1D can suffice. The thing is, however, that we are not dealing with cartesian coordinates.

Hi  Johannes,

I hope you are well, did you recieved my letter I sent Monday to your Colleague  Prof Dr Klaus Dieter Weltmann, I cannot disclose this letter on this forum because it's Glycan R&D Plan for Deep Space and Pharmacy because Swiss patent on writing., kind regards Christian

Hi, I suppose you would not have any real dynamical process in your plasma (of course dissociation and recombination are dynamical processes, but I expect the macroscopic fields such as Temperature, density and potential would not evolve, they would be in a steady state, or slowly evolving state, right) ?

So, a priori, no annoying plasma instability ? So basically it would be a "simple" boundary condition problem ? You give the potential and density on the walls, and you deduce potential, current and temperature in the plasma, and finally you can deduce the dissociation rate by its tabulated value as function of density and temperature ? If it is just this, it should not be too difficult to simulate your mathematical model, even if something must be written from scratch, maybe. What is the heating source for the plasma in your model ? What mathematical model do you use ? Can you send the paper you published previously ?

Hi Johannes

welcome on board !

congratulations for your works and plans

For manned mission forget it for long trip and works on planets or moons more than one year , untill we cannot protect astronauts from solar and cosmic radiations, our DNA must be protected- this has been demonstrated by prof Charles Limoli Uni of Irvine ( cancerology )- and also with COLATERAL effect of development of neurodegenerative disease as well as AD Alzheimer Disease like- we work a lot on this and patent recently new route and Engineering for AD. 19.06.2019-

It will 10 years of ROBOTIC (with AI Artificial Intelligence ) capabilities) missions on Mars and others planets or moons(it's very important point.

But also we need for Mars to remake the atmosphere because CO2- Helium ideal for plasmas- we work from 2006- at 2019 with USPTO 2016-2017 plasma patents PCT 2018 China-Russia-Europe-India-Israel.

YES i will be happy to share with you , and plan future works my be a Lab of simulations of Solar and cosmic waves, and cells cultures with and without drugs to protect and also GENESIS lab for the atmosphères to be recreated, we will need Colleagues in Solar and GEOCHEMISTRY compétences from local ground we can also generate water and atmosphères like in the past of these objects.

Also to go to and trip to space, go to the Solar system supermarket on asteroids or planets or moons we must clean the space debris, if not soon we will loose our jobs and industries.

HAVE A NICE WEEK END

KIND REGARDS

TOGETHER WITH OTHERS , YES WE CAN! even "with couple of greens"
