Subject: Pressure curve rounded and flame quenching in n-propanol + hydrogen blend
Dear Ansys Forum,
I am simulating an SI engine fueled with n-propanol enriched with hydrogen. Despite using a 0.2 mm mesh, optimized time steps, and adjusted combustion parameters, my pressure curve remains rounded and the flame quenches early. The solver log shows "flame has quenched completely." Any advice on resolving this issue would be appreciated. I have pinned two images related to pressure and turbulent
flame speed too, see the attachmentsThank you.
