What is Recirculation Length 2
 

Hi

I need to know what the recirculation length is or in short a brief description. I have read a previous post on this but was a little confused by the answer.

I have a figure with the flow around a cylinder. the recirculation length is from 0 to 1 where zero is the separation point and 1 appears to be straight through the centre of vorticies formed in the wake. (I can send the picture ifthis makes no sense.

Thanks in advance
