Shock-wave/boundary-layer interactions in the automatic source-code generation framework OpenSBLI

Laminar shock-wave/boundary-layer interactions were simulated using OpenSBLI, a Python-based source code generation framework. Shock-capturing was performed by a 5th order finite-difference Weighted Essentially Non-Oscillatory (WENO)-Z scheme applied in characteristic space. Oblique shock conditions were imposed for a shock angle of θ=32.58∘ and Mach 2 free-stream, impinging on a laminar flat-plate boundary-layer. Performance of the code was assessed on different architectures for CPU, GPU and Xeon Phi.

Abstract

Laminar shock-wave/boundary-layer interactions were simulated using OpenSBLI, a Python-based source code generation framework. Shock-capturing was performed by a 5th order finite-difference Weighted Essentially Non-Oscillatory (WENO)-Z scheme applied in characteristic space. Oblique shock conditions were imposed for a shock angle of θ=32.58∘ and Mach 2 free-stream, impinging on a laminar flat-plate boundary-layer. Performance of the code was assessed on different architectures for CPU, GPU and Xeon Phi.
