EFFECT OF STABILIZING LENGTH IN STRAIGHT CORE ANNULAR DIFFUSER

Abstract

A diffuser is a device for converting the kinetic energy of an incoming fluid into pressure. As the flow proceeds through the diffuser there is continuous retardation of the flow resulting in conversion of kinetic energy into pressure energy. Such a process is termed as diffusion. Diffuser forms an important part in flow machinery and structures. The present study involves the CFD analysis for the prediction of flow characteristics using various mathematical models. The straight core annular diffuser considered in the present case has increasing stabilizing length at different divergence angle and area ratio. The flow patterns have been presented for studying at stabilizing length d and 3d for different divergence angles.
