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 air and water and assume that liquid air and gaseous water (vapor) exist.
The properties of each phase of gas and liquid, as well as their constituent substances air and water, 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 both the gas and liquid phases.
The meshes are as follows, and the number of mesh is 1875.
Meshes
The calculation result is as follows.
Air in the liquid phase at final time (air.liquid)
Water in the liquid phase at final time (water.liquid)
Air in the gas phase at final time (air.gas)
Water in the gas phase at final time (water.gas)
