Performance Analysis of Backward curved Centrifugal fan in Heating Ventilation and Air-conditioning
Journal Title: UNKNOWN - Year 2013, Vol 2, Issue 6
Abstract
In this paper, a performance analysis of the backward curved centrifugal fan has been carried out. Centrifugal fan is mostly used in HVAC, and in this a theoretical analysis is done using CFD. As a first step, modeling based on specifications is done. Then, CFD TOOL Autodesk CFD 2013 is used for performance analysis of the fan. During analysis blade angles is varied, and its effect on static pressure and total pressure of the fan is investigated. Also, theoretical analysis on the same lines has been developed. In this study, theoretical results obtained are compared with that obtained using CFD tool by drawing a performance curve for different blade angles. This is helpful is selecting the appropriate fan. The purpose of this paper is to give a better understanding of the performance behavior under different aspects to improve the design of the fan.
