Inlet velocity for particles in eulerian two phase flow
 
Can anybody tell me what velocity for the particle will be taken at inlet for the following parameters.

Particle diameter = 0.0005m
Density = 700 kg/m3
Volume fraction of particle = 0.005
Air velocity = 15 m/s
Pipe dia = 0.1m

Its a two phase flow of air and particles inside a pipe . when I give no slip velocity at inlet , solution is converged , but the continuity of the particles is not satisfied.

Also for high values of volume fraction , there is problem in convergence.
Can any body figure out the root cause.

Thanks
PP
