A detailed literature survey is presented herein in order to overview the aerodynamic impact
of non-radial blade stacking techniques applied to axial flow fan and compressor rotors. The …

The paper discusses the use of sweep as a remedial strategy to control the aerodynamic
limits in low-speed axial fan rotors. In this respect, the present work contributes to the …

Large axial flow fans are used in forced draft air cooled heat exchangers (ACHEs). Previous
studies have shown that adverse operating conditions cause certain sectors of the fan, or the …

Comparative studies have been carried out on two axial flow fan rotors of controlled vortex
design (CVD), at their design flowrate, in order to investigate the effects of circumferential …

Fan is one of the main noise sources of the room air-conditioners. Axial flow fans are widely
used in the outdoor unit of split type air-conditioners. The interaction between the fan and …

An axial flow fan design methodology is developed to design large diameter, low pressure
rise, rotor-only fans for large air-cooled heat exchangers. The procedure aims to design …

A computational study is presented which investigates the predictive performance of a non-
linear turbulence closure in simulating the flow physics pertinent to a high-pressure axial …

The heat transfer characteristics of industrial air-cooled heat exchangers (ACHEs) are
dependent on the ability of the fan system to deliver sufficient cooling air. However, under …

In modern turbomachinery blade design, nonradial stacking of the profiles is often assumed
to be one of the ways to improve the performance of a machine. Instead of stacking the …

This study assesses the effectiveness of modified blade-tip configurations in achieving
passive noise control in industrial fans. The concepts developed here, which are based on …
