F26 - Scale-resolving simulations
and modeling of
momentum and heat transfer in turbomachinary



Organizers: T. Zaki & Y. Hasegawa

Tamer Zaki is an associate professor of mechanical engineering at Johns Hopkins University. His research activity spans high-fidelity simulations of transitional and turbulent shear flows, interfacial flows, complex fluids and multi-scale modeling. He received his PhD in 2005 from Stanford University where he participated in the Department of Energy Advanced Simulation and Computing (DoE-ASC) program. He subsequently joined the Department of Mechanical Engineering at Imperial College London (2006) where he established the Flow Science and Engineering group, followed by his current appointment at Johns Hopkins.


Yosuke Hasegawa is a lecturer at the Institute of Industrial Science (IIS) at the University of Tokyo. After receiving his PhD in 2004 from the University of Tokyo, he was appointed as a research associate of the 21st Century Center of Excellence Program at the University of Tokyo. From 2010 to 2012, he worked at the Center of Smart Interfaces at TU Darmstadt as a visiting professor supported by the Japan Society for Promotion of Science. In 2012, he joined IIS. His research interests include modeling of heat and mass transfer across interfaces, optimal control of turbulent heat and momentum transfer, shape optimization of energy devices, and modeling of heat and fluid flow in micro two-phase flow.

The main goal of this Forum at the ISROMAC16 Conference is to discuss the most recent advances in the simulation and modeling of turbulent flows using scale-resolving method such as Large-eddy simulation (LES), hybrid methods (combining statistical approaches such as LES and RANS) and their applications to the turbine and compressor stages of turbomachinery.


Non-exhaustive list of suggested Topics:

- Wall-treatment of high-Reynolds-number flows

- Boundary conditions for unsteady flow aerodynamics (e.g. Synthetic Eddy-methods)

- Hybrid RANS-LES as a zonal approach

- Novel analysis techniques of high-fidelity Direct and Large-Eddy Simulations

- Advances and limitations of existing LES and hybrid models

- Modeling and control of turbulent heat transfer
