F31 - High performance CFD
in Turbomachinery

Organizers: L. Mangani & M. Darwish

Luca Mangani is serving as an Associate Professor at the fluid mechanics and hydro-machines department, where he manages a variety of projects with industrial partners aimed at developing advanced and novel CFD tools. He has been also actively working in numerical technique research and development for turbo machinery applications. His CFD research interests include pressure and density-based solvers, segregated and fully coupled algorithms, fluid-structure interaction (FSI), turbulence, conjugate heat transfer and combustion modeling.

Marwan Darwish is a professor of Mechanical Engineering at the American University of Beirut. He has been actively working in CFD research and development for over 25 years, with several journal publications. His areas of interest include:numerical schemes, all speed flows, multiphase and particulate flows, free surface flows, advanced numerics and algorithms all within the context of the finite volume method.


The history of Fluid machinery is closely linked to the development of propulsion and energy conversion systems. Decades of experimentation and theory development have resulted in continuous improvements in the efficiency of these systems. The successful development and application of CFD over the past thirty years has resulted in the routine use of numerical simulation as an essential engineering R&D tool for analysis, design and lately for design optimization.
The new generation of fluid machinery will require more efficient, robust algorithms and numerics that are applicable to the investigation of more complex physics and geometries to explore the limits of actual and new designs.
This forum addresses many of the areas where numerical advances will be needed, namely: pressure and density-velocity coupling, hardware acceleration, physics complexity, computational scalability, HPC, higher accuracy schemes, improved models, analysis and design optimization techniques, fluid structure interaction methods , minimization of the pre-processing, new mesh generation and adaptivity.
