[OpenFOAM] Heat transfer coefficient - calculation + display in ParaView

atlan · July 24, 2014, 04:24

Hi,

Can anyone advise me how to calculate local heat transfer coefficient in OpenFoam and then display it in ParaView? I am able to calculate wallheatflux and the wall temperature. I would like to use the local temperature of the flow for the heat transfer coefficient calculation, but I do not know how to do it.

Thanks
Atlan

It is perfectly explained here, at the end of this TFD Chalmers tutorial:

Once NusseltCalc is execute, a new field is created and you can visualize the results in paraview:

Pd; For next time, try google first (is faster).

Hi, im very new in openFoam, and i want to calculate the heat transfer coefficient, and the global heat tranfer coefficient from my simulation(buoyanSimpleFoam).

I saw the link above, but it's no clear for me, I tried to modifi, the postprocess utility but with out success.

could you explain me in detail?

I will really appreciate it
