Heat transfer with SST

HI!
I´m using the SST model in CFX 5.5 to predict heat transfer from an impinging jet on a cylinder. When I´m using a grid with a y+ of 0-12 I get good result (compared to similar cases in the literature), but now I have refined the grid near the surface so I have a y+ of 0-1, then I don´t get the same result. I get a very increased rate of heat transfer on a spot on the side of the cylinder that I believe should not be there. Does anyone else have the same or related problem? /Eva |

- Do you compare with measurements or simulations in literature?
- Which wall function do you use? - What do you mean by 'the side of the cylinder'? - Are you sure transient phenomena like vortex shedding do not occur? This will influence you heat transfer.... /Astrid |
