Hi,
I’m simulating combustion in a closed chamber using the species transport model. The setup includes a dense mesh, pressure-based solver, transient simulation, and the energy equation is activated. I’m using the standard k-epsilon model for viscosity, with ethylene as fuel and air as the oxidizer. All boundaries are set as walls. For initialization, I’ve specified the mass fractions of O2 and ethylene. A spark plug is used to ignite the combustion.
However, the results I’m getting show either constant pressure or temperature increase, which doesn’t align with the expected behavior I’ve observed in similar simulations.
Any suggestions would be greatly appreciated!
