axisymmetric burner weird temp contour
 
hi,



I am creating an asymmetric model for a diffusion burner, for now I setup up the model as non reacting and all velocity inlet BCs at T=290K , However when i run it , i get this temperature contour which i dont expect since all T=290 for air and multi component gas inlets , I have pressure outlets as extrapolated. Any advice would be greatly appreciated. I dont get it why the temperature rises at pressure outlet. I am using K-epsilon standard model (segregated flow) and you can also find a photo for my mesh.

Hi,
'asymmetric' <- you mean axisymmetric right?
Can you show velocity, pressure profile and residual plot also?
