Numerical analysis of fluid flow in fork tube with circle cross section

A series of analyses of flow loss in three types of fork tubes with circle cross section were made to investigate an optimal angle degree for designing of fork tube in the Yixing power plant. Renolds averaged equations with k e turbulence model are solved to numerically simulate fluid flow in the fork tube. The models used the SIMPLE algorithm. The calculated results show that fork tube with angle degree of 64 is the best one among fork tubes with angle degree of 64, 74 and 84 by comparing energy loss between inlet and outlet. They also show that results of calculation are accordant with experimental data.
