ABSTRACT

Branched pipes appear in many practical applications such as electrical power plants, engineering machines, and blood vessels. These pipes consist of an inlet pipe and two outlet pipes; the joint between the inlet pipe and the outlet pipes is a 90° angle. In this investigation the flow structure is captured using the particle image velocimetry (PIV) method, carried out using a tracer illuminated by a YAG laser at Reynolds numbers 450 and 840. As a result, the existence of the characteristic flow structure is confirmed even in a T-branch rectangular pipe, the same as in the case of the T-branch circular pipe. Moreover, a pair of swirling flows is observed in the direction of outflow even in the T-branch rectangular pipe.
