Research Fellows Directory
Professor Graham Hargrave
Research interests are concentrated in the area of Optical Engineering, with emphasis on the development and application of laser diagnostics for fluid flow, multi-phase flow and combustion studies. Research emphasises the importance of developing an understanding of the fundamental physics of flow and combustion processes; the knowledge gained from experimental studies being encapsulated within predictive mathematical models to aid future design processes. Highly active links with academic and industrial partners world-wide and industrial collaborations include Jaguar Cars, Shell, Perkins Engines, Caterpillar, E.ON, 3M, Astra-Zeneca, and Chiesi Pharmaceutici. Academic collaborations with universities in the UK (Aberystwyth, Leeds, Sheffield, Durham, Nottingham, UCL, City University and Oxford University) and internationally (CNR, University of Naples and Kyoto University).
Research work addresses many aspects of optical diagnostic development and application for flow and combustion research. I have projects investigating (i) atomisation processes in asthma inhalers, (ii) injector/mixer design for SCR after-treatment system for low NOx, low CO2 engines, (iii) mixer design and optical sensor development for gas turbine combustors, (iv) optical analysis of phase separators for engine coolant applications, (v) design of multi-point gas injection systems for dual-fuel engines, (vi) diesel engine in-cylinder flow characterisation for CFD model validation, (vi) optical diagnostic investigation of cold-start operation of SI engines, (vii) a study of cavitation processes in high-pressure fluids, and (viii) dynamics of runoff and erosion processes to determine mass transport in overland flows and droplet impacts in heavy rain storms.
