Referencing calculated values (rho)

Hi everyone,
I am trying to calculate the wall heat transfer coefficient in a setup with a compressible solver using polynominal coefficients as described here by Tobias Holzmann. So far this works fine. I try to calculate the heat transfer coefficient using the functions in the control dict as shown in this part here: Code:
{ #include "$FOAM_CASE/constant/cooling_water/thermophysicalProperties"; type wallHeatTransferCoeff; libs ("libfieldFunctionObjects.so"); region cooling_water; patches ("cooling_water_to_aussen"); rho 998; Cp 4180; Prl 0.707; Prt 0.9; } Code:
Unable to find incompressible turbulence model in the database I tried to reference with the following without success: calculated / $rho / $rho() / $rhoCoeffs / $rhoCoeffs<8> Can anybody help me? Best regards Michael |

Hi,
The documentation of wallHeatTransferCoeff (v8) states that the utility is only for incompressible flow simulations. It also seems that you are aware of this limitation. (or are you?) The utility simply complains only about this. Could using heatTransferCoeff (v1712) instead help?

Hi HPE, thanks for reply. As I started this thread I thought there may be a possibility to get the values for the calculations. Meanwhile I was going over to use ParaView to calculate HTC. I found some other problems which need to be solved first at my simulation. Nevertheless, I think in a next HTC-simulation I will try the ESI version. Michael |
