June 11, 2018, 06:04	Two phase simulation with Corey model doesnt match analytical result	#1
missmeow New Member Tianqing Wang Join Date: Mar 2018 Posts: 2 Rep Power: 0	Hello everyone, I'm doing a intermediate two-phase flow of oil and water into a vertical well with Corey model(nw=no=3, swi=sor=0.2; krwmax=kromax=0.8), the volume flow rate of well is compared with analytical solution by Darcy equation. Water flow rate at high water saturation is higher than analytical solution, mesh convergence conduction doesnt help. I checked reference and changed parameters to nw=no=5, swi=sor=0.2; krwmax=kromax=0.5, which are according to the nature, then the figure shows good match. Can somebody explain why it's like this? Thanks! failure2.PNG 21.PNG
