large osillation in species
 
1 Attachment(s)
Hi, I am having my CFD model with chemical reaction with species transport. The attachment below is part of my result. I validate my CFD result with matlab result which has been validated with experiment. I found that the CFD result seems to oscillate nearby the matlab result. Is it due to the large gradient in numerical setting in Fluent? Do I need to reduce the URF of species from 1? Any suggestion to improve my CFD result? Please help. It is urgent. Please
