Solver for heat transfer calculation with water media

Jan 27, 2011Which solver should I use for a heat transfer calculation using water media. I though about using buoyantSimpleFoam but it seems that the solver deals with (perfect) gas only. Is the solution to derive a new solver from buoyantSimpleFoam? Thx for your help Benjamin SAUTHIER January 20, 2006, 05:21

Sensible heat is the heat that causes a temperature change when there is a heat transfer, e.g., heat moving through the walls of a home causing a temperature rise. Latent heat is the heat that causes a change in state but no change in temperature, e.g., heat that is absorbed when ice changes to water or when boiling water changes to vapor.
