CFX wall heat transfer coefficient

mactech001 · January 5, 2010, 21:05

Dear all,

I would like to transfer the wall heat transfer coefficient (HTC) from CFX into ANSYS WB to perform a thermal analysis with fluid cooling.

i understand i need to check how the HTC is computed in CFX, whether it is using near wall temperature or ambient temperature.

how can i check this setting please?

I always get the following message in my .out files. I think it answers your question quite nicely:

+--------------------------------------------------------------------+
| ****** Notice ****** |
| Wall Heat Transfer Coefficient written to the results file uses |
| "Wall Adjacent Temperature" for the bulk temperature. If you want |
| to override the bulk temperature then set the expert parameter |
| "tbulk for htc = <value>" |
+--------------------------------------------------------------------+
