Mesh element for velocity and pressure drop prediction

sache · July 23, 2014, 04:12

Hello,

If i have two wall with some 400 mm gap and air is flowing through it, how many element (in cross section) i should put in while meshing to get velocity and pressure drop. velocity is around 2 m/s and temperature around 200-300 degree Celcius. Is is ok to put 2-3 elements in it.

thank you.

No, it is not. It slightly depends on your solver too, but I would probably go with at least 40 cells.
