Thank you, indeed I can see some diffusion.
I tried also the case of two gases at different temperature. Also in this case, diffusion occurs. I compared results obtained with reactingFoam and rhoCentralFoam for temperature diffusion: 1) For very high viscosity, both simulations give same results; 2) For real viscosity values, diffusion is much more faster in rhoCentralFoam. I have to invastigate further and compare numerical results with analytical solutions. I don't know if anyone else has encountered these strange behaviors of the solvers. Thank you |

First of all, reactingFoam seems to work well. The problem is with rhoCentralFoam. If I set viscosity: ![]() I got these results:
https://we.tl/t-C0GA4p2ap3 It's really strange beacuse for inviscid flow, rhoCentralFoam should directly avoid to solve Navier-Stokes equations. Thank you |
