How can i find particle sediment thickness on pipe wall ?? (sediment bed thickness) thank's for any help akhshik likes this.

 June 17, 2012, 17:06 #2 New Member   sina Join Date: May 2012 Posts: 8 Rep Power: 7 i do it by this Assumption : fluid inlet velocity = 7.5 volume fraction = 0.1 horizontal case inner wall rotation =61 rpm solid phase velocity = 0.5 number of mesh 2,600,000 countinuty converge up to 10e-05 in 600 iteration result = 2200 pa but it must be around 1176 please help me ,what cause this reason? by changing solid phase velocity can i make it right?

Are you using transient simulations ?? I am unable to get my simulation converged ??? I wonder if you could guide me in this..

Velocity Magnitude and Volume Fraction for liquid and solid should be determined for software.
