Sand velocity depending on the flow velocity -- CFD Online Discussion Forums

July 12, 2017, 07:21	Sand velocity depending on the flow velocity	#1
ealzeraim New Member Erhamah Join Date: Jun 2017 Posts: 2 Rep Power: 0	Hello, I am trying to simulate granular flow using Eulerian mode. I have a problem with defining the velocity of the secondary phase (sand). The velocity of the primary phase is defined as velocity magnitude and it is equal to 4.5 m/s. I want to redefine the velocity of the secondary phase as stated in the attached pictureScreenshot_20170712-151943.jpg I think I should use UDF, but am not sure how. Please assist me.
