Flow over a cylinder -- CFD Online Discussion Forums

March 7, 2006, 22:36	Flow over a cylinder	#1
Anna Guest Posts: n/a	Hello, I'm doing a research about the flow over a circular cylinder. I have a few things that I don't understand. My questions are: 1) What is the difference between horizontal cylinder, vertical cylinder, circular cylinder and vertical/horizontal circular cylinder? 2) I found that in some paper, they used the cartesian coordinate in the equation for this problem. Some other paper used cylindrical polar coordinate in the equation. Is it we can use any coordinate for this problem or there is a certain condition in choosing the coordinate? Can somebody help me? -Anna-
