Multiphase flows are found in a large number of industrial processes including power generation, pharmaceutical and chemical industry or agriculture. The production of chemical goods worth billions of dollars and the generation of several hundred trillion Joules of primary energy depend on the safe and efficient handling of multiphase flows. Hence their control and accurate numerical prediction are of paramount importance for the development of future generation high efficiency cost effective engineering devices.
Key challenges associated with the modelling of such flows include their multiphysics and multiscale nature involving interactions of turbulence, interface physics, phase change and chemical reactions on temporal and spatial scales spanning several orders of magnitude. In the last two decades, progress in numerical methods and computing power allowed impressive direct numerical simulations (DNS) of multiphase flows that considerably improved our physical understanding of such flows. However, as DNS is limited to academic configurations in the foreseeable future, the development of next generation models for large scale, or averaged multiphase flows is an important challenge.
The lecture will introduce several recent applications of Multiphase flows and its modelling and discuss unexpected challenges.
Markus Klein is Full Professor for Numerical Methods in Aerospace Engineering at the University of the Bundeswehr Munich, where he is also Dean of the Faculty of Aerospace Engineering. He received his doctorate and habilitation from the Technical University of Darmstadt, with research focusing on direct numerical simulation and modelling of turbulent reacting and multiphase flows. His career includes postdoctoral research at the University of Cambridge and several years in industrial engine development at Adam Opel AG, most recently as head of department. His research interests span turbulence modelling, large-eddy simulation, multiphase and reacting flows, and the development of predictive models for complex technical flows. Prof. Klein has authored numerous journal publications, holds several patents, and serves as associate editor for Flow Turbulence and Combustion and Nature Scientific Reports.
