Lift Coefficient -- CFD Online Discussion Forums

June 7, 2021, 08:33	Lift Coefficient	#1
Prantik Das New Member Join Date: Jun 2021 Posts: 5 Rep Power: 5	[CENTER]I am putting a constant lift coefficient of .5 which is for spherical solid particles and is simulating a slurry flow through a pipeline. But when I am calculating the lift coefficient and lift force I am getting the value of Cl () -------------------------------- ------------------- wall -524.48261 Lift (n) -------------------------------- ------------------- wall -321.2456 Why? I had chosen a lift coefficient of .5 and now they are showing Cl= -524.48261. I have chosen the component format of velocity in velocity inlet boundary condition and taken same velocity of 3m/s for both solid and liquid phase.
