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". We assume that the ratio of water to air is 1:1 in the region "inlet", and the calculation is performed as a two-dimensional problem with one mesh in the z-direction.
The properties of the air and water are set in the files "constant/phaseProperties", "constant/thermophysicalProperties.air", and "constant/thermophysicalProperties.water". In the file "constant/phaseProperties", "type heatAndMomentumTransferTwoPhaseSystem" is also set.
The meshes are as follows, and the number of mesh is 1875.
Meshes
The calculation result is as follows.
