Sarah.g New Member Join Date: Jul 2020 Posts: 8 Rep Power: 5	Hi everyone, I am doing analysis of rocket engine in the low ambient pressure (0.4 Pa, Kn:0.11). I am using Eddy-dissipation concept as turbulence- chemistry interaction model in species transport with 9 chemical reactions. Viscous model is k-e. I couldn't make convergence for the analysis. Do you think this problem is caused by meshor turbulence model?
