MEMS Fall 2021 Seminar Presents: Dr. Chunlei Liang of Clarkson University Presented August 25th, 2021 Location: Fitzpatrick Schiciano-B 1466 and in ZOOM, Zoom link: In this talk, a novel high-order sliding-mesh algorithm for solving compressible Navier-Stokes equations on unstructured grids will be presented. This high-order method is validated against experimental data for turbulent flows around a marine propeller operating at the design condition. Subsequently, the method is applied to analyze the performance of a ducted wind turbine at a Reynolds number of 1.25 Million. The computational results clearly show that the ducted turbine has higher thrust and higher power outputs than the open-rotor turbine. Vorticity and velocity fields of two configurations are also visualized and analyzed to show the differences.
