Hi, I have simulated flow past circular cylinder at Re of 40 and am able to capture the attached vortices downstream of the cylinder. Now, I want to measure the circulation of both the vortices. Is there any simple way to measure it? Shall I plot vector plot of velocity in tecplot and create a closed contour around which we get circulation automatically?

search for "biot savarts law" on internet which will tell you how to measure circulation of vortices(some good pdfs are available). If you can't find get back to me I will mail you some pdf's.
I am also working on low reynolds number flow around a pair of square cylinders. My code is able to capture the vortices downstream but I don't have any concrete data to validate my code. Do you have any literature on the same? |

hi, thanx for your reply.. I will search for it.. I have references for flow past two square cylinders. But what exactly your Re and in which form they are arranged?

I am analysing flow upto Re 120. The two square cylinders are in line with their faces perpendicular to the direction of flow and separated by some distance. I hope this much description will help you in visualizing the domain.

Dear Omkar
I am modeling 3D piston\cylinder vortex generator in ANSYS CFX. My reynolds is above 2000. Is there any way to calculate the circulatin in CFX-post? Regards |

Hi sudhakar
I am working on the flow over the circular cylinder using my own code. What are the datas you have consider to validate your code. |
