The blower is among the key components in any industrial applications like boilers, cooling systems, dryers etc. Hence the performance and the characteristics of the blower affect the whole system and the efficiency of the work. The blower system consists of mainly three parts suction hood, impellor and volute which determine the characters of the blower. It is very important to predict the air flow for a blower before its application. A study on the industrial centrifugal blower is done to accurately predict the air flow and mass flow using Computational Fluid Dynamics (CFD) tool. The detailed model of blower is created with the help of a 3D CAD Software and a 3D CFD Fluent code is used to solve different governing equations and predict the flow at outlet of the blower. The numerical results obtained with the help of CFD are compared with the characteristic curve supplied by the manufacturer. © 2017 Elsevier Ltd. All rights reserved.
