Rotating flow is critically important across a wide range of scientific, engineering and product applications, providing design and modeling capability for diverse products such as jet engines, pumps and vacuum cleaners, as well as geophysical flows.Developed over the course of 20 years' research into rotating fluids and associated heat transfer at the University of Sussex Thermo-Fluid Mechanics Research Centre (TFMRC), Rotating Flow is an indispensable reference and resource for all those working within the gas turbine and rotating machinery industries.Traditional fluid and flow dynamics titles offer the essential background but generally include very sparse coverage of rotating flows-which is where this book comes in. Beginning with an accessible introduction to rotating flow, recognized expert Peter Childs takes you through fundamental equations, vorticity and vortices, rotating disc flow, flow around rotating cylinders and flow in rotating cavities, with an introduction to atmospheric and oceanic circulations included to help deepen understanding.Whilst competing resources are weighed down with complex mathematics, this book focuses on the essential equations and provides full workings to take readers step-by-step through the theory so they can concentrate on the practical applications. - A detailed yet accessible introduction to rotating flows, illustrating the differences between flows where rotation is significant and highlighting the non-intuitive nature of rotating flow fields - Written by world-leading authority on rotating flow, Peter Childs, making this a unique and authoritative work - Covers the essential theory behind engineering applications such as rotating discs, cylinders, and cavities, with natural phenomena such as atmospheric and oceanic flows used to explain underlying principles - Provides a rigorous, fully worked mathematical account of rotating flows whilst also including numerous practical examples in daily life to highlight the relevance and prevalence of different flow types - Concise summaries of the results of important research and lists of references included to direct readers to significant further resources

Peter Childs, FREng, is the Professorial Lead in Engineering Design and Innovation Design Engineering. He is Professor at Large, Co-Director of the Energy Futures Lab, and was Founding Head of the Dyson School of Design Engineering at Imperial College London. His general interests include creativity, innovation, design, fluid flow and heat transfer, energy and robotics. Prior to his current post at Imperial, he was director of the Rolls-Royce supported University Technology Centre for Aero-Thermal Systems, director of InQbate and professor at the University of Sussex. He has contributed to over 200 refereed journal and conference papers, and several books including the Handbook on Mechanical Design Engineering (Elsevier, 2013, 2019) as well as temperature measurements and rotating flow. He has been principal or co-investigator on contracts totaling over £100 million. He is Editor of the Journal of Power and Energy, Professor of Excellence at MD-H, Berlin, and Chairperson at BladeBUG Ltd and Founder Director and Chairperson at QBot Ltd.
