| Summary | 0000315: chemFoam solver produces incorrect results for constant volume simulations |
|---|
| Description | The pressure equation used for constant volume simulations assumes that the average molecular weight of the reactor remains constant, as R0 is never updated from its initial value.
The result incorrect calculation of pressure which, of course, affects all the other variables of interest. The most obvious error is that internal energy is not constant during the simulation. |
|---|
| Steps To Reproduce | Run chemFoam with volume held constant. Compare with results from Cantera or Chemkin constant volume simulation for the same initial conditions. |
|---|
| Additional Information | Fix is to update R0 on each time step to account for change in average molecular weight of mixture. |
