Dear senior users,
I would like to ask about the capability of Flow3D. I'm doing a study of local scour downstream of a hydropower station. The stilling basin has 160cm and 11cm, length and width respectively and the sediment size is 0.1cm, 0.2cm, 0.6cm and 1cm.
As I read the sediment scour model, sediment grain size should be less than 10% of mesh cell size. Also, the cell size ratio couldn’t more than 2 times. Thus, the cell size of mesh blocks in my case should be 0.5cm, 1cm for stilling basin and 2cm for packed sediment. But 2cm-cell size is big for mesh quality but not enough for packed sediment model.
Is Flow-3D possible to simulate scour depth in this case? Any solutions to solve the problem above?
Is there another numerical model suitable in this case?
I’ll appreciate your help. Thank you.
