Nusselt_Sphere_Whitaker class
Contents
Description
This is a sub-class of the Nusselt class for the implementation of the Whitaker correlation for computing the Nusselt number for a flow past a sphere.

Notation:
: Reynolds number
: Prandtl number
: Fluid viscosity at fluid temperature
: Fluid viscosity at particle surface temperature (assumed to be equal to the fluid temperature value)
