i try to solve solid liquid mixture flow with eulerian method in anuular pipe
my primary phase is drilling mud with density 1300
solid phase is sand with diameter 3mm
i know the average axial velocity and volume fraction,but i dont know the particle velocity!! is it enough that i just give volume fraction to solid phase or i must give the particle velocity too??
How can i find particle sediment thickness on pipe wall ?? (sediment bed thickness)
thank's for any help :)
i do it by this Assumption :
fluid inlet velocity = 7.5
volume fraction = 0.1
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?:o
Did you find the answer to your problem ?? i am also trying to simulate solid liquid slurry flow in pipes.. 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.
