David Clarke Fellow


Dr. Ruoyang Yuan is a David Clarke Fellow EPSRC. Her current work focuses on the low-carbon energy conversion and propulsion technologies. She has a strong research background in advanced optical diagnostics, fluid machinery and fluid mechanics, turbulent combustion, heat transfer, multiphase flows and with gas turbine application and internal combustion engines.  Previously she was a researcher in the Thermal & Aerodynamic Systems Engineering (TASE), Jaguar Land Rover, working on thermal management modelling and energy optimisation for hybrid powertrains. Dr. Yuan joined Loughborough in 2015 as a RA working on endoscopic optical diagnostics for in-cylinder combustion and emission analysis, funded by the Advanced Propulsion Centre (APC) in collaboration with Caterpillar Inc. to aid the design of low emission diesel engines. Dr. Yuan’s research activities includes optical diagnostics such as particle image velocimetry (PIV), phase doppler anemometry (PDA), planar laser-induced fluorescence (PLIF), Raman scattering, Mie scattering, laser extinction and laser induced incandescence (LII), laser induced breakdown spectroscopy (LIBS), endoscopic multi-colour pyrometer, chemiluminescence and multicolour soot pyrometry and numerical modelling using Computer-aided engineering (CAE), computational fluid dynamics (CFD) in heat transfer, laminar/turbulent reacting flow, COSILAB and CHEMKIN for chemical reaction simulation, Powerflow/Powertherm for flow and heat transfer, GT-SUITE for vehicle/powertrain modelling.
