COMPUTATIONAL FLUID DYNAMICS (CFD) ANALYSIS OF RECTANGULAR MULTI BAFFLED CHAMBER USING ANSYS FLUENT

Abstract

ABSTRACT In this Dissertation, using ANSYS Fluent software (R14.5) computational fluid dynamics (CFD) analysis of 3D Rectangular Baffled Chamber is done. The Model consists of combination of vertical standing as well as hanging angled baffles. Flow patterns are taken into consideration. The dead zones and stream lines together with velocity vectors are analyzed of chamber by changing number of baffles in terms of spacing and the discharge coming into the chamber. In a finite volume, the numbers of chambers form 4 to 6 are increased by reducing the spacing in terms of width between them and discharge from 10 liters per hour to 50 liters per hour is varied to value of less, equals and more than the capacity of chamber. The combination of stream lines and Velocity vectors covering maximum area of chamber is presented which will increase the (baffling performance) efficiency as well as the effective volume utilized. In results, the velocity graph at locations i.e. near bottom, mid depth and near surface of models containing different number of chambers is shown. The Results obtained can be used in further improvement of ABR design.
