I have a steel plate where the bottom wall is heated. Above this solid plate, a water-filled zone is there which is contained by side adiabatic walls made up of steel. Above this static water zone, a zone filled with air is present. The air is incoming and outgoing as shown in the figure.
The air is modelled as a species with a combination of dry air+ water vapour. The water is also getting evaporated based on pressure difference and vapour formed is getting mixed in the air zone. Note : 3 frozen bodies are made in the design modeller and then all are made to form new parts. Can anyone guide me on how to do this? cfd.PNG |

seems like you've done it already isn't it?
so you have 2 zones solid and fluid. fluid is a mix of water and air. after initialization patch water part of fluid zone with water = 1 set boundary conditions

Quote:
Zone 1: Solid(steel) Zone 2: fluid(water) Zone 3: fluid( dry air+ water vapour) Zone 2 is static liquid is contained within walls Zone 3 is air moving from inlet to outlet I tried doing this, but I am not getting proper results. I am doing a steady state analysis. But the result are absurd. |
