Dr Rajnish N Sharma
PhD (Fluid dynamics) - Auckland; BE Hons 1st Class - Auckland
Dr Rajnish Sharma is a Senior Lecturer in the Department of Mechanical Engineering, the University of Auckland, specialising in the subject areas of Aerodynamics, Fluid Dynamics, Heat Transfer, Thermodynamics, and their application. He has been an academic here since August 2001, and became a permanent member of staff in 2007.
His academic career commenced at the Fiji National University (formerly Fiji Institute of Technology), and later, he joined the University of the South Pacific (USP) in Suva, Fiji, as a Lecturer in Mechanical Engineering. After completing a PhD in Fluid Dynamics / Wind Engineering at the University of Auckland in 1996, on a USP-NZ Government Fellowship, he returned to USP and helped with the accreditation of a new Bachelor of Engineering Technology degree programme (curriculum development, lab development) and setting up / commencing a Postgraduate Programme of Study before migrating to NZ in July 2001.
Since 2008, Dr Sharma has supervised 6 PhD’s and several ME’s to completion, and is currently mentoring 13 more PhD’s as principal supervisor, and several others as co-supervisor.
He currently serves as the Academic Head of the new Thermofluids Laboratory at Newmarket campus, and, represents the Department on the Faculty Equity Committee. He has previously served on many significant committees of the Department, Faculty and the University (both at USP and the UOA).
Over the years, Dr Sharma has developed collaboration with several industries and research institutes, and regularly provides consulting services to clients from outside of the University. He has also served on organising and scientific committees of several international conferences over the years.
Research | Current
His research utilises computational (cfd) and experimental methods, and, include (but not limited to) the following: Unsteady aero-fluid dynamics of lifting surfaces at low Reynolds numbers (UAV wings, turbine blades); Unsteady hydrodynamics of tidal turbines; Aerodynamic analysis of novel wind turbine systems; Wind engineering and building aerodynamics; Pesticide spray drift; Industrial fluid mechanics; Synthetic and continuous jet flow turbulence, interactions, and their impingement fluid/thermal/heat transfer dynamics; Ultra micro gas turbine (UMGT) systems (micro-combustor, micro-turbine); Micro fluidics and micro combustion; Micro scale thermal management technologies; Industrial theral-fluid dynamics; Natural and wind induced ventilation; and more.
