Introduction to Axial Flow Fan

The aim of this work is to assess the degree of reliability of MULTALL as a tool for simulating the internal flow in industrial axial-flow fan rotors.

In this paper, atmosphere plasma spray (APS) is used to prepare WC/Ni coating on 1Cr18Ni9Ti stainless steel to enhance the wear resistance of materials of the axial-flow fan.

Several rotors of axial-flow fans and side channel blowers with optimal circumferential spacing have been tested in a hemi-anechoic chamber; such rotors have been designed by means of an existing method based on the minimization of the tonal noise peaks prominence from the broadband spectrum.

As the critical equipment, large axial-flow fan (LAF) is used widely in highway tunnels for ventilating.

The new casing is made by open-cell metal foam, and its effect on both aerodynamic and acoustic performance of an axial-flow fan is investigated experimentally.

The paper deals with the aerodynamic performance of ducted axial-flow fans available in the 2020 market and aims to create a general picture of the best designs and design trends, as a tool for fan designers.

The effect of a casing fence on the tip-leakage flow of an axial flow fan is investigated using large eddy simulation.

In turbomachinery field, axial flow fan is the most important component of the rotatory system as it increases the pressure rise and improves fan characteristic.

The air with carbon dioxide is made to flow through the reaction chamber using an axial flow fan and NaOH is sprayed using a nozzle.

Computational fluid dynamic models are utilized to compare the destratification capability of a simple vortex ring generator operating at two different Richardson numbers with an axial flow fan.

In this paper, Reynolds-averaged Navier–Stokes equations with the standard k−e turbulent model and Multiple Reference Frame model were used to simulate the performance of axial flow fan.

In this study flow around an axial flow fan is investigated by the means of CFD computations using the commercial software package, ANSYS Fluent.

The improvement in efficiency of axial flow fans is major concern in turbomachinery industries including outdoor units of air conditioners.

Performance improvement in axial flow fans is a popular research topic that is typically explored by changing the blade shape and tip clearance of the leading edge or trailing edge.

The present results show that: under design conditions, the total pressure efficiency of the axial flow fan with the forward swept blade is the highest, and the C-type blade has slightly lower efficiency while the straight blade has the lowest efficiency.

A circular-type pod silencer has been designed to reduce a high noise level generated from an axial flow fan.
