Check cases for turbulance heat transfer on a complex shape

Dear Sir I am working on turbolent heat transfer problems by finite volume method and try to write a code as general as possible for a special case. to see wether my code works well or not I need some test cases for turbulent heat transfer phenomena on a complex shape. but unfortunately the present codes I know are only for simple cases.that would be very kind of you to introduce me some... Yours Faithfully abedi

Dear Mehdi,

Can you explain more about the flow geometry.

In order to get a nice temp. field, you must resolve the flow and turbulence fields (specially near the wall) very well. So before looking at heat transfer I think you should make some comparisons for flow.

Re: Check cases for turbulance heat transfer on a complex shape

Dear Sir I have solved the flow over any complex shape for my special case and I am sure that the flow field soloution works well.but as you know in finite volume method there are source terms which depends on grid generation over field .for this reason when i am going to solve the energy equations over this field I have to check the solution for insurance,not only for the simple cases which their meshes are some how uniform or in a good conditions but also for complex shapes which have nonuniform meshes to check wether source terms are good or not

thanks for your attentions M. Abedi

Re: Check cases for turbulance heat transfer on a complex shape

(1). In turbomachinery, the cavity flow heat transfer is always an important problem. There, the cavity geometry is not always a rectangular cavity. (2). Try to look into the ASME/Journal of Turbomachinery, in the area of cavity flow heat transfer. (3). There is also a more important heat transfer problem, that is the HP turbine blade heat transfer with internal cooling. I am sure that you will be able to find something in this area too.
