LIU Zheng

Liu Zheng received his Master’s degree in Automotive engineering from University of Bath in 2015. In 2015, He started the PhD study at University of Bath in the Powertrain and Vehicle Research Center focusing on the designing, mapping, and optimising the mixed flow turbines especially under unsteady flow conditions. During his PhD study, he had participated in several funded industrial research projects as a research co-investigator, including experimental testing of automotive turbochargers, optimisation of the compressor intake duct, balancing the thrust force of a twin-
compressor using CFD (computational fluid dynamics), one-dimensional optimisation of a steamed Inverted Brayton Cycle for waste heat recovery.

In June 2019, he joined Nanyang Technological University as a Research Associate. While at CARES, his research project was in collaboration with Daimler AG and focused on the aerodynamic optimisation of a novel turbocharger twin-entry turbine for a better fuel economy of automotive engines.
