I have some doubts regarding the PEMFC simulations If you can answer them it will be very helpful to proceed ahead.
1. It was noticed that ,Mostly the experimental data reported in research papers and literature review is not reliable, so where I can find the reliable experimental data.
2. Currently I am running steady state simulations of single cell fuel cell with 0.1 million cells but simulations are taking around 3 days to converge with 4 parallel processes. So what how much computational power is required for PEMFC simulations? (would like to know about System configuration)
3. If you can connect me with people who are working in this field it will be really helpful. I am trying my best to get every possible information and inputs to complete this project If you can help me with above queries I will be very much thankful of you. Thank you!!!
Dear Bhambure
1. It is ought to be said that the data sets available in literature are incomplete هn terms of needed parameters to be fitted not being reliable. The possible solution would be to search for ones that more used by various researchers. You can also investigate various works of the researchers whose data set is opted by you to find more parameters form their recent papers.
2. I propose you firstly start with a single channel particularly when the channel geometry is parallel to see if you can reach to the true values. At the second pace, start simulation of the single cell with coarse mesh to obtain a faster convergence and also an initial results. Then you can refine the mesh to check the mesh independency and maybe better results.
you can use a supercomputer from any university if it is available, it reduces the time of iterations
Thank you sir Majid Shateri and Abbas J Jubear for answer.
Yes, I am using Single cell configuration as base case, solution is also converging but it takes around 300000 iterations for convergence which takes around 3 days time using 4 parallel processes.
I would like to know what suitable computer system configuration is required for PEMFC simulations.
If you can suggest the reliable source of information (research papers) regarding reliable experimental data it will be very helpful.
Thank you!!!
I have not seen such a specific paper dedicated to computer configuration for PEMFC modeling. If you will find any, please reference it here.
But you can find related information spread in related articles. Try searching keywords like "ram", "cpu time", "pem fuel cell", "fluent" and "CFD" in Google scholar.
