Collaborative Research: Effects of Wall Curvature on Hypersonic Turbulent Spatially-Developing Boundary Layers
Abstract
Summary: Study concave/convex wall curvature on supersonic/hypersonic SDTBL (Mach numbers up to 5) in a suite of high spatial/temporal resolution Direct Numerical Simulation (DNS) as well as Implicit Wall Resolved Large Eddy Simulation (iLES) at high Reynolds numbers. Research Objectives: 1) Evaluate the effect of:(i) wall-curvature driven pressure gradient, (ii) flow compressibility, (iii) Reynolds number dependency, and (iv) wall temperature on low/high-order statistics of the flow and turbulent structures based on high fidelity DNS. 2) Explore iLESs performance in complex flows. Highlights of Approach: Highly scalable finite-element flow solverPHASTA (Parallel Hierarchic Adaptive Stabilized Transient Analysis)1 Turbulent compressible inflow generation via the Dynamic Multi-scale Approach (DMA)2 Efficient and speedy post-processing library for large scale CFD systems.
