High-order Sliding-mesh Spectral Difference Method for Petascale Simulations of Turbulent Flows Around Marine Propellors
Abstract
Fluid flows around rotating geometries are very common in engineering applications. Examplesinclude flows around marine propellers, wind turbines, and helicopter blades, to name just a few. Theseflows are usually characterized with many vortical structures that are known to have significant impacton the performance of the system. To accurately simulate them, the computational fluid dynamicscommunity has been facing two major challenges over the past decades. The first one is to controlnumerical dissipation which is detrimental to flow structures. The second is to incorporate the complexrotating geometries into a flow solver without deteriorating the accuracy and efficiency.The objective of this research project is to develop a new high-order accurate and highly efficientsolver to tackle these challenges for complex rotating geometries such as marine propellers. This solverwill be further optimized to become highly scalable for petascale simulations. It will be used to predictturbulent flows around open and ducted marine propellers at large Reynolds numbers with both explicitand implicit time stepping methods and automatic polynomial refinement technique.
