| Presentation Title |
From drop impact physics to spray cooling models |
| Abstract |
| In this seminar the hydrodynamics and thermodynamics involved in drops impacting onto hot surfaces will be examined for a large range of drop Reynolds and Weber numbers as well as for a large range of surface temperatures, typical of industrial spray cooling situations as encountered in quenching or cooling of high performance electronics. Building on high-speed visualization of drop and spray impact onto hot surfaces and using local measurements of heat flux and drop impact parameters, analytical models are formulated for the main regimes of thermodynamic interaction – natural convection, nucleate boiling, thermal atomization, film boiling. These models are then applied to predict spray cooling scenarios, in which hot surfaces are cooled from temperatures exceeding the Leidenfrost limit. These predictions are validated and refined using corresponding experiments in which all necessary measurement quantities are captured. |

| Cameron Tropea graduated from the University of Toronto in Engineering Sciences, followed by a Masters degree in Mechanical Engineering (1977). He completed his Dr.-Ing. in Civil Engineering at the Technical University of Karlsruhe (1982) and his Habilitation in Fluid Mechanics at the University of Erlangen-Nürnberg (1991) where he was appointed as Professor of Fluid Mechanics until 1997. This was followed by an appointment to his current chair of Fluid Mechanics and Aerodynamics at the Technische Universit?t Darmstadt. Currently Editor-in-Chief of the Springer journal Experiments in Fluids and past Director of the Center of Smart Interfaces (CSI) in the period 2007-2014, his research interests include Optical Measurement Techniques in Fluid Mechanics, Interfacial Transport Phenomena, Atomization and Spray Processes and Unsteady Aerodynamics. He has been a member of the Scientific Commission of the Council of Science and Humanities in Germany since 2016. |
