About

Overview

Dr Qiang Zhang received his Ph.D. in Mechanical Engineering from the University of Utah in 2005 and held a Research Assistant Professorship at the University of Utah in 2006. From 2006 to 2010, he was a research staff in the Osney Thermo-Fluids Laboratory at the University of Oxford (Rolls-Royce Heat Transfer and Aerodynamics University Technology Centre), where his work mainly focused on transonic turbine blade aero-thermo research. Dr. Zhang has been an Associate Professor at the University of Michigan & Shanghai Jiao Tong University Joint Institute since 2010. From 2014, Dr. Zhang returned to Uk and currently works as a Senior Lecturer in Aeronautics with City, University of London.

Dr. Zhang’s research interests include gas turbine heat transfer and cooling, aerodynamics, conjugate heat transfer, experimental techniques and CFD application. He has published nearly 50 journal papers (J. Turmocach., Physics of Fluids, AIAA, etc.), and held two US/UK/EU patents. He was elected as ASME Fellow in 2019 and currently served as Associate Editor for ASME Journal of Thermal Science and Engineering Applications

Awards

  1. InnovateUK (2017) Concentrated Solar Power micro gas turbine with thermal energy storage (SolGATS)
    The project aims at the development of a concentrated solar power (CSP) parabolic dish system generating electricity using a micro gas turbine (MGT) with thermal energy storage using solid particles, which can be used in combined power, heating and cooling. The aim is to advance current MGT-CSP technology developed by City University and integrate it with a solar dish technology and high temperature thermal storage using solid particles developed by Zhejiang University to provide an optimised system that can produce energy from solar power reliably while minimising the need for back up power thus maximising environmental benefit. The system is an alternative to CSP-Sterling technology that suffers from poor reliability and difficulty to integrate with thermal storage. The innovation arises from system and component level developments allowing the efficient and reliable integration. The technology can be deployed in standalone mode or stacked in a flexible manner for medium power plants. The advantages over Photovoltaic arise from the integrated energy storage, reduced land use, tri-generation and higher efficiency particularly in hot climates with direct sunlight.
