Axis Boundary Condition..what is it? -- CFD Online Discussion Forums

February 1, 2007, 15:14	Axis Boundary Condition..what is it?	#1
CFDtoy Guest Posts: n/a	I am modeling a gas-in-gas process, gas exiting from a cirular tube into still air. I am using a 3D slice with periodic boundary condition and an axis boundary condition. Could someone tell me what does an axis boundary condition do? Is it symmetry or some kind of reflecting boundary condition? how are the flow variables computed near the axis type? Thanks for the clarification CFDtoy
