Detailed Description

A thermal wall function for simulation of subcooled nucleate wall boiling with runtime selctable submodels for:

- wall heat flux partitioning model

nucleation site density
bubble departure frequency
bubble departure diameter

Implements a version of the well-known RPI wall boiling model (Kurul & Podowski, 1991). The model implementation is similar to the model described by Peltola & Pättikangas (2012) but has been extended with the wall heat flux partitioning models.
