Cfd Simulation Of Flow Field In An Inject Pipe Mixer

The Inject Pipe Mixer (IPM) are being used as venturi injectors and can also homogenize two fluids. The entry of secondary fluid as a jet influences flow field in the device. A CFD simulation of flow through an IPM (Lshape) has been carried out using ANSYS CFX 11.0 using water as the flowing fluid to understand the flow field under turbulent flow conditions using standard k--ε model. The results of simulations indicate flow field dependence on both main pipe velocity and side pipe inlet velocity. The flow field depends on V and W components and U component contributes very marginally. The velocity magnitude depends on location inside the geometry.
