Centrifugal fan aerodynamic and rotor dynamic study

Abstract

The aim of this paper is the design of the desired fan. In this case, we have conducted both theoretical and numerical types of study using Solid-works to get the wanted results. We will study the performance of a centrifugal fan and its capacity for lifting the required air volume flow rate. The aim of this study is to check the capacity of the (FN 501) centrifugal fan to lift a minimum mass flow rate of 10 tons/hour when we connected to the (FL 301). Fan performance is usually presented in the form of a characteristic curve of air volume flow against the pressure developed by the fan. In the first part, we will plot these curves using fan laws, and then we will design the fan and simulate it using CAD software (Solid-works). In the second part we will design the dust collector filter and the duct system, and then run a CFD simulation to get the system pressure drop curve. The fan operational point will be the intersection of the fan curve and the system curve pressure drop curve
