Philipp Epple is a visiting scholar at CUSP. He has been a full Professor for fluid mechanics and turbomachinery at the department of mechanical engineering of the Coburg University of applied sciences in Germany since 2011. He teaches classes of introductory and advanced fluid mechanics, classes of introductory and advanced turbomachinery, numerical fluid mechanics (CFD), thermodynamics, heat transfer, wind energy and related fields. He has been the head of the group of turbomachinery and process fluid dynamics at the Institute of Fluid Mechanics of the University of Erlangen for several years. He received his doctoral degree in mechanical engineering with honours from the University of Erlangen. He has worked in the design, development and CFD computation of turbomachines, having done uncounted CFD computations for a large variety of machines, like for example fans, ranging from some centimetres to over two meters in diameter, wind turbines, also an high velocity ICE train, big waste water and small blood pumps. He has also done simulations of building aerodynamics and of small roof top wind turbines. He has built more than 15 test rigs for turbomachinery and performed measurements on more than 300 turbomachines. He worked on over 40 industry projects in the field of turbomachines and fluid mechanics. He has supervised about 100 master and several PhD theses. He has more than 100 publications in international journals and peer reviewed conferences. He is a member of the ASME, AIAA and of the VDI. He is also an associate editor of the ASME Journal of Fluids Engineering as well as a member of the Executive Committee of the Fluids Engineering Division of the ASME (American Society of Mechanical Engineers).
