Assessment of a Machine-Learnt Adaptive Wall-Function in a Compressor Cascade With Sinusoidal Leading Edge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Near-wall modeling is one of the most challenging aspects of computational fluid dynamic computations. In fact, integration-to-the-wall with low-Reynolds approach strongly affects accuracy of results, but strongly increases ...
On the Role of Leading Edge Bumps in the Control of Stall Onset in Axial Fan Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Taking a lead from the humpback whale flukes, characterized by a series of bumps that result in a sinusoidallike leading edge, this paper reports on a threedimensional numerical study of sinusoidal leading edges on cambered ...
A Critical Review of Passive Noise Control Techniques in Industrial Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This review aims to assist engineers in understanding and applying passive solutions for reducing industrial fan noise. The paper systematically reviews the extant literature on passive noise techniques, with a particular ...
A Machine-Learnt Wall Function for Rotating Diffusers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Data-driven tools and techniques have proved their effectiveness in many engineering applications. Machine-learning has gradually become a paradigm to explore innovative designs in turbomachinery. However, industrial ...
Simulation of the Deposit Evolution on a Fan Blade for Tunnel Ventilation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fans used in tunnel ventilation operate for decades in an atmosphere that carries dust, soot, and other solid particles. The formation of deposit on the rotor blades, considering a so long time of exposition to this ...
Morphing of Reversible Axial Fan Blade: A FSI-FEM Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reversible axial fans are widely used in industrial and tunnel ventilation systems, and a lot of research effort is spent in the design process of the blades shape and blades profile. The target is to achieve reasonable ...
Design of a Tip Appendage for the Control of Tip Leakage Vortices in Axial Flow Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article reports on numerical investigations of passive control techniques used for the performance enhancement of a large diameter axial flow cooling fan through modification of the blade tip geometry. Using open-source ...
Numerical Simulation of Coal Fly Ash Erosion in an Induced Draft Fan
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Induced draft fans extract coalfired boiler exhaust gases in the form of a twophase flow with a dispersed solid phase made of unburnt coal and fly ash; consequently fan blades are subject to erosion causing material wear ...
Numerical Testing of a Trailing Edge Passive Morphing Control for Large Axial Fan Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The concept of morphing geometry to control and stabilize the flow has been proposed and applied in several aeronautic and wind turbine applications. We studied the effect of a similar passive system applied on an axial ...
Numerical Simulation of the Blade Aging Process in an Induced Draft Fan Due to Long Time Exposition to Fly Ash Particles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Erosion issues usually affect fans used for the extraction of exhaust gas in power plants. Because of the presence of fly ash within the exhaust flow, fan blades are subjected to material wear at the leading edge, trailing ...
