Abstract

Flow features and vortex shedding in the wake zone behind V-shaped bluff bodies are experimentally investigated. These experiments were done for a single V-shaped body at various Reynolds number between 4.84 x 104 - 5.91 x 104, span angles between 45°-90°, and angles of attack between 0 and 15o . Experiments were also made for two V-shaped bluff bodies arranged in tandem and in the same vertical plane with different spaces between them. With the aid of a water tunnel, the phenomena of vortex shedding and flow recirculation behind the V-shaped bluff body were illustrated. Results show that the increase of Reynolds number monotonically reduces the length of the recirculation zone. A similar flow structure of the flow exists among near wake flows of V shaped bodies with different span angles. Increasing the span angle, the size of the recirculation zone increases. The variation in attack angle changes slightly the size of the recirculation zone and shifts the recirculation zone vertically. For the two bodies arranged in tandem, the size of the recirculation zone increases as increasing the spacing between the two V-shaped bodies. For the two bodies in the same vertical plane, decreasing the spacing between the two bodies yields to earlier mixing between the flows in the two wakes.
