A computational fluid dynamics (CFD) analysis has been conducted to find the pressure losses for dividing and combining fluid flow through a junction of discharge system. Simulations are performed for a range of flow ratios and equations are developed for pressure loss coefficients at junctions. A mathematical model based on successive approximations then would be employed to estimate the pressure losses. The proposed CFD based strategy can be used for the analysis of all the three pipe branches of some diameter are selected along with equal length so that only the effect of bend angle can be studied. The effect of bend angle, pipe diameter, pipe length, reynolds number on the resistance coefficient is studied. The software used is CATIA for modeling and ANSYS fluent for analysis purpose.
