Summary
Model geometry
We calculate the mixing of air into the water column for 100 seconds. Air flows in from the region "inlet" at the bottom of the water column at (0, 0.1, 0) m/s and out from the region "outlet". The calculation is performed as a two-dimensional problem with one mesh in the z-direction.
We consider the phase change of water and assume that gaseous water (vapor) exists.
The physical properties of the gaseous and liquid phases and their constituent substances air and H2O are set in the files "constant/phaseProperties", "constant/thermophysicalProperties.gas" and "constant/thermophysicalProperties.liquid". In the file "constant/phaseProperties", the "multiComponentPhaseModel" type is specified for the gas phase and the "purePhaseModel" type is specified for the liquid phase.
The meshes are as follows, and the number of mesh is 1875.
Meshes
The calculation result is as follows.
Volume ratio of liquid at final time (alpha.liquid)
Vapor at final time (H2O.gas)
