CFD Analysis of Annular Curved Diffuser

Abstract

In this thesis the characteristics of flow within a circular cross sectioned annular curved diffuser is investigated at different mass flow rates and divergence angles. The divergence angles considered are 9⁰, 15⁰, 21⁰, 27⁰, 33⁰, 39⁰. CFD analysis is done all the diffuser models by changing mass flow rates 0.02259Kg/s, 0.04518Kg/s & 0.09036Kg/s to determine static pressure, velocity, pressure coefficient and turbulent kinetic energy. 3D modeling of the annular curved diffuser models are done in Creo 2.0. CFD analysis is be done in Ansys 14.5 to determine the flow characteristics.
