Autor: Sam Bull, Nicola Chiereghin, David J. Cleaver

Publikováno v: Bull, S, Chiereghin, N & Cleaver, D 2022, ' Compounding Transient Airfoil Motions and the Effectiveness of Linear Superposition ', AIAA Journal, vol. 60, no. 10, pp. 5768-5778 . https://doi.org/10.2514/1.J061640

This paper investigates, for the first time, the effects of compounding transient airfoil motions and the predictive capability of the linear superposition principle in vortex dominated flows. Significant increases in the peak lift and nose-down pitc

Novel Approach to Leading-Edge Vortex Suppression

Autor: David Cleaver, Ismet Gursul, Nicola Chiereghin, Samuel Bull

Publikováno v: Bull, S, Chiereghin, N, Cleaver, D J & Gursul, I 2020, ' Novel Approach to Leading-Edge Vortex Suppression ', AIAA Journal, vol. 58, no. 10, pp. 4212-4227 . https://doi.org/10.2514/1.J059444

A novel approach to reduce the peak lift and pitching moment on a plunging airfoil is investigated through force, moment, and velocity measurements. This approach, unlike previous investigations of delayed flow separation and leading-edge vortex supp

Delayed Detached-Eddy Simulation and Particle Image Velocimetry Investigation of S-Duct Flow Distortion

Autor: Daniel Gil-Prieto, Nicola Chiereghin, David G. MacManus, Pavlos K. Zachos, Francois Wilson, Geoffrey Tanguy

Publikováno v: AIAA Journal. 55:1893-1908

The dynamic flow distortion generated within convoluted aeroengine intakes can affect the performance and operability of the engine. There is a need for a better understanding of the main flow mechanisms that promote flow distortion at the exit of S-

Publikováno v: 23rd AIAA Computational Fluid Dynamics Conference.

The Free Form Deformation method was applied to a S-duct geometry to reduce total pressure losses and flow distortion. The deformation method was coupled with a multi-objective genetic algorithm to optimize the shape of a diffusing S-duct, which was
