Reply To: Mass Conservation Issue in Methane Pyrolysis Shock Tube Simulation

[Vijay Narayan]

Hi Ghislian, 

I would like to know a few more details:

a) are the walls adiabatic ? and how is the energy conservation for all the 3 cases.

b) Could you share a snippet of the density contour for the 3 reacting cases before and after the point the mass imbalance increases. 

c) Will the CH4 case also show mass imbalance if run further because i could see for H2 imbalance started at ~0.25ms and for CO2 case at 1ms

d) what are the mach numbers expected in the simulation and could you also share the residual plots for either of the H2 and CO2 case.

e) Could we try with Segregated solver and FO schemes and see if the results improve ?
