Ash/Air multiphase heat exchanger -- CFD Online Discussion Forums

May 20, 2009, 09:34	Ash/Air multiphase heat exchanger	#1
pantarei83 New Member Antonio P. Join Date: Mar 2009 Posts: 10 Rep Power: 17	I'm simulating an heat exchange between air and ash inside a multiphase cooler. I did a preliminar analysis supposing a restitution coefficient for walls equal to 1, and the run reached quickly convergence. But when I switched the restitution coefficient for walls equal to 0.05, the run didn't reach convergence. Wich parameters could I modify or set to solve the problem? Thanx
