Modelling of two phase flow in packed bed using conservation equations

[QUOTE="Chestermiller, post: 6560862, member: 345636"] Regarding the heat capacities, do you really want to consider these temperature-dependent? At least for this crude model, I would treat them as constants. Do you not have available to you an automatic ODE implicit integrator like the GEAR package on the IMSL library or DASSL (available for free online)? Of course, these are FORTRAN programs. Is there no such software available with PYTHON? It would make life so much easier for you, since these packages have automatic time step size control, automatic order control, and automatic accuracy control, and all you need to do is provide coding for calculating the time derivatives. If you are going to integrate these equations manually, I strongly recommend going fully implicit. You are certainly going to have to do this (for stability control) when you solve the actual PDEs for the time- and spatial model. [/QUOTE]
