FDTD Simulation of flow through tapered pipe -- CFD Online Discussion Forums

December 18, 2006, 12:45	FDTD Simulation of flow through tapered pipe	#1
Jim Guest Posts: n/a	Hi, I have a basic flow simulation problem. I have set up a finite difference flow simulation program for fluid flow through a straight pipe (using 2D parabolic wave equation ut = uxx + uyy). I would like now to taper the pipe to a very small diameter. The same code does not give the correct behavior, before or after the taper region. Has anyone out there encountered and/or solved this type of system? Thanks for your help!
