Finding the drag and lift coefficients at any given location

Djphx · January 9, 2019, 06:25

Hi,
I am simulating a flow around a 3d circular cylinder. I know how to obtain the cd and cl values with time for a transient model but am unaware of how to get the cd and cl values at each location (spanwise/ lengthwise). Please help.

Thanks in advance

Cd and Cl are integrated properties and do not exist locally. What you are looking for is not Cd and Cl. So you need to clarify.....

Hi,
Is there a way to get the cd and cl values integrated over a fixed length of area (like cd and cl values integrated over the location/total length ratio of 0 to 0.1 and 0.1 to 0.2 and so on)?
