The Flow Past a Surface-Mounted Obstacle

The length of the recirculating region past a two dimensional obstacle was investigated experimentally with a single hot wire. The width (W) of the obstacle could be changed in multiple values of obstacle height (H). The results show that upstream of the obstacle the length of the main recirculating...

Description
Summary:The length of the recirculating region past a two dimensional obstacle was investigated experimentally with a single hot wire. The width (W) of the obstacle could be changed in multiple values of obstacle height (H). The results show that upstream of the obstacle the length of the main recirculating region remains unchanged with obstacle width and equal to 0.85H; however the downstream length of the recirculating region is a strong function of the width and changes almost linearly from 11 obstacle heights for W/H=1.0 to 3 for W/H greater than four.
