Detailed Description

A thermal wall function for simulation of subcooled nucleate wall boiling with runtime selectable 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 based on implementation described in Peltola et al. (2019) and is similar to the model described by Peltola & Pättikangas (2012). The present implementation includes simplified support for presence of non-volatile components in addition to a single volatile component.
