movement of bed river soil
hi friends
i am working about movement of soil particles from bed river when water flows with high velocity in river. how can i define this soil of bed river to simulate this movement?? i am really confused. any body know that? thanks a lot ashkan |
Do you want to include scouring of a bed of soil and/or deposition of the soil to form new shoals? Or just the motion of the soil in the moving water?

hi ghorrocks
i want to simulate scouring of a bed around bridge pier. i dont know how can i do that in cfx. |
CFX cannot simulate scouring directly. It does not have a physical model built into it to handle this. You may be able to use the fluidised bed models but I doubt it as it was not developed for this purpose.
The best approach would be to either couple CFX with a DEM model such as EDEM, or to use a different CFD code with scouring models built in. |
define time
thanks my friend
you helped me. i have another question. how can i define the 35 minutes time for my simulation? i want to see the differences between simulating in 2th minute and in 15th and 35th minutes. so how can i simulate for 35 min and then extract 2th and 15th min from that simulation? |
All times are GMT -4. The time now is 11:23. |
