Abstract

An energy equation, based on an enthalpy function, representing phase change under convection and diffusion is developed. This equation is easily formulated into the general transport-equation form and its application in the PHOENICS code in the modelling of phase change problems is readily achieved. Two examples of phase change problems are modelled by this approach:
  1. i

    solidification in a square cavity under heat conduction only,

     
  2. ii

    solidification in a square cavity under heat conduction and natural convection.

     

A comparison of the PHOENICS results with available analytical solutions and purpose written numerical codes is made.
