funkyDoCalc for OpenFOAM post-processing

May 24, 2021 Leave a comment Nima Samkhaniani OpenFOAM

The own OpenFOAM post-processing tools are : postProcess and foamCalc. However, funkyDoCalc is a hell of tools. It makes life easier. If you missed run-time processing by an accident, and you don’t like to redo the simulations you may still can derive some results from saved data in time directories.

Nusslet Number is a dimensionless number and usually reported in heat transfer context. It is defined as:

${\frac {hL}{k}}={\frac {{\left.{\frac {\partial \left({{T}_{s}}-T\right)}{\partial y}}\right|}_{y=0}}{\frac {\left({{T}_{s}}-{{T}_{\infty }}\right)}{L}}}$
