calculate Nusselt number

yassine.bt · June 8, 2020, 16:31

I am working on buoyantSimpleFoam (). I have got some results from my simulations. Now I need to calculate the Nusselt Number from my simulations. Can anyone tell me how to calculate Nu number from OpenFOAM simulations?

As far as I know there is no post process utility that does if for you.

However, you could do it "by" hand by simply using the formula for Nussel number and your own post processing utility.

option 1: paraview: use the calculator to compute your nusselt number in your domain. you can visualiz it then.

option 2: postProcess lib: if there doesn't exist one, you could write your own, if you have programming skills.
