Under-relaxation Factors for Solid-Gas flow -- CFD Online Discussion Forums

January 11, 2013, 11:14	Under-relaxation Factors for Solid-Gas flow	#1
bbmorales New Member Bayard Morales Join Date: Aug 2009 Posts: 24 Rep Power: 16	Hello there. I am running simulations using Fluent 14.0 of gas-solid flows in reactors as Fluidised Bed, Circulating Fluidised Bed and Spouted Beds. My modelling is Euler-euler, with a granular phase with diameter ranging from 2010^-6 to 2010^-4. I am attaining convergence, but I would like to know if any of you have any advice regarding the Under-relaxation factors for this kind of simulation, in order to allow me to employ larger time-steps. Thanks in advance.
