CFD analysis for the performance of Gurney flap on aerofoil and vertical axis turbine
Yan, Y; Avital, E; Williams, JJR; Korakianitis, T (International Journal of Mechanical Engineering and Robotics Research, 2019-05-01)© 2019 Int. J. Mech. Eng. Rob. Res. A numerical study was carried out to investigate the effects of a Gurney flap on the aerodynamics performance of the NACA 0018 aerofoil and an associated three-blades rotor of a H-type ... -
A computational model of ureteral peristalsis and an investigation into ureteral reflux.
Hosseini, G; Ji, C; Xu, D; Rezaienia, MA; Avital, E; Munjiza, A; Williams, JJR; Green, JSA (2018-02)The aim of this study is to create a computational model of the human ureteral system that accurately replicates the peristaltic movement of the ureter for a variety of physiological and pathological functions. The objectives ... -
