Shuji (大友衆示) attained his Bachelor's degree in Mechanical Engineering in 2017 from Hokkaido University in Japan. His research project was to investigate the effect of turbulence on Savonius turbine under the supervision of Prof. Yuichi Murai and Dr. Yuji Tasaka at LFC (Laboratory for Flow Control) collaborated with Dr. Petr Denissenko of the University of Warwick. He has experimentally shown that Savonius turbine shows a better performance in a turbulent flow subjected to Richardson-Kolmogorov cascade by using hot-wire anemometry (HWA) and particle image velocimetry (PIV). During his BSc, he was awarded a scholarship from Japan Student Services Organization (JASSO) for his PhD study under the supervision of Dr. Ignazio Maria Viola.
He is experimentally and analytically investigating unsteady aerodynamics of a flapping foil in a massively separated flow through the impulse theory.
He stayed at UNFoLD (Unsteady Flow Diagnostics Laboratory), EPFL, Switzerland between October and December 2018 for the collaboration with Dr. Karen Mulleners, to investigate the fluid mechanics of a pitching wing.
He is also a part-time research assistant to develop a low-order model of the tidal energy harvesting device for Tidal Flyer Ltd.
