Hello members,
Currently I am working on the "phase change simulation of fluid in an AC system". I have following doubts in the working procedure. Aim is to show how the phase change from vapor changes to liquid in a specific medium like water. 1.What is the preferred wall treatment for the codnesation in the k-epsilon turbulent model? 2. The phase change was carried out with VOF model, phase interactions>mass>evaporation condensation. Is this proper way to define condensation process or should I look for process in eulerian? 3.The geometry is quite complex, what should be the file type for import? parasolid was not able to create mesh. STEP file was taking too time to read in meshing process.What is the preferred wall treatment for the codnesation in the k-epsilon turbulent model? 4.What are the efficient methods to build meshing and type of meshing to speed up the further simulation? 5.I am doing my simulation in an academic version, with constraint of nodes constraint. What are common practices in meshing to reduce the overall number of nodes in meshed object? The time required to run the simulation is way too high(it almost took 2 hrs just to simulate 4 sec ) |
