Title: COOLFluiD: High-Order Methods for Transitional Hypersonic Flow Modelling

Speaker: Ray Vandenhoeck  (KU Leuven, CmPA)


Resolving the thermal and aerodynamic loads acting on high-speed vehicles, such as reusable launcher stages that travel primarily in the hypersonic regime, requires high-accuracy Computational Fluid Dynamics (CFD) methods that can handle complex geometries and are well suited to massively parallel high-performance computing. Additionally, prediction of the onset and extent of the transition from laminar to turbulent flow is particularly challenging and crucial in the design of such vehicles. High-order finite element-type methods show great promise in accurately and efficiently resolving such flows. However, they are in their infancy for high-speed flows with strong shocks, as well as for laminar-turbulent transition modelling. 
In the present work a fast and robust parallel flow solver based on high-order finite element-type methods is developed within the COOLFluiD platform. Such methods exhibit a much higher accuracy per degree of freedom in the computational mesh as compared to traditional low-order methods and allow for calculating more accurate solutions on relatively coarser computational grids. Additionally, a novel shock capturing scheme for the high-order finite element-type Flux Reconstruction (FR) method is developed in order to accurately resolve flows with strong shocks in a robust way. Finally, a novel Local Correlation-Based Transition Model (LCTM) for the Reynolds-Averaged Navier Stokes equations (RANS) to predict laminar-turbulent transition is incorporated. This LCTM is based on the Langtry-Menter model, while having a more physics-based transport equation for the intermittency. 
The accuracy and performance of the solver is investigated for several verification cases. Furthermore, the FR code is successfully applied to several hypersonic reference cases. Good agreement is shown both with numerical and experimental data. Finally, the RANS solver is also applied to the flow around a representative high-speed vehicle, i.e. the HIFiRE-5. The results are compared to both numerical and flight data.
