Pressure drop in laminar flow -- CFD Online Discussion Forums

August 24, 2007, 06:26	Pressure drop in laminar flow	#1
carno Guest Posts: n/a	I have solved a laminar flow problem. The Re number is 0.2. The objective is to calculate the pressure loss in the system. But the CFD simulation is giving around 17% errors. Sometimes the errors are positive and sometimes negative. I tried different mesh densities but in vain. What could be the reason? Has anybody faced such problem?
