Description:

A number of examples are presented which illustrate important difficulties of numerical calculations and experimental comparisons. The existence of multiple solutions with the same boundary conditions is discussed in terms of the Taylor vortex problem. We show that the history of the flow is important in numerical and experimental flow development and that generally numerical and experimental approaches are complementary. Difficulties of comparing numerical solutions with either numerically generated data or experimental information are discussed with reference to two-dimensional natural convection and three-dimensional Rayleigh-Benard convection in bounded domains with conducting boundaries. Finally, it is shown that non-dimensionalisation is not an appropriate tool when dealing with fluids in thermally driven flows in which there are significant changes in transport properties in the temperature range used to drive the flow.

Biography:

Professor Reizes is at present Adjunct Professor at the University of New South Wales and at the University of Technology, Sydney. He was awarded the Henderson Memorial Prize in 1976 by the Institution of Mechanical Engineers, London for his paper on the performance of centrifugal slurry pumps and more recently. In 2006, the College of Mechanical engineers has awarded him the AGM Michell Medal, its highest honour for his contribution to the profession, sustained leadership in the development of mechanical engineering the and for his contribution to the art and science of Mechanical Engineering. He has made seminal contributions on physio-chemical effects in slurry flows. He is internationally recognised for his numerical work in heat transfer and fluid mechanics with over 170 publications in the international literature. He led the team which invented and developed an implantable rotary blood pump, which is to be a permanent implant for people with failing hearts. The pump is at present in clinical trials. He is a past Chairman of the College of Mechanical Engineers, a past Editor of the Mechanical Transaction of the Institution of Engineers Australia and is at present the Chairman of the Australasian Fluids and Thermal Engineering Society. He is, and has been, an active member of Organising Committees of many National and International Conferences including being Treasurer of the Organising Committee of the prestigious International Heat Transfer Conference to be held in Sydney in August 2006. He has served on the Engineering 2 Panel of the Australian Research Council (ARC) and on the ARC Collaborative Grants Committee. Although he retired from the University of Technology, Sydney in 1999 as Associate Dean Research, he has remained active in research, having received an ARC Discovery Grant of $A520 000 for the next three years.
