Overview
| Solver Capabilities | : | – Two incompressible fluid – Non isothermal fluid – Immiscible fluid – Phase change (evaporation-condensation) between a fluid and its vapor – VOF (volume of fluid) phase-fraction based interface capturing approach – Lee phase change model |
| Computational case | : | 2D flat plate test case from Vyskocil, L. Schmid, J., Macek J. CFD simulation of air-steam flow with condensation. Nuclear Engineering and Design, 2014. |
The case is described in the following figure.
Wet steam flows through a flat plate. One side of the wall is being cooled thus condensate will appear on that side.
Mesh
The 2-dimensional structured mesh is created using base mesh of CFDSOF.
