Abstract

High fidelity DNS simulations of the complex flow physics of a hypersonic boundary layer interacting with the coolant flow of a porous surface require a multiscale simulation approach. We employ a high-order hybrid WENO scheme, multiblock domain treatment in conjunction with massively parallel computating and an efficient mesh adaptation methodology to tackle this problem. In the present work, we describe the algorithmic components of our novel approach and show the results reached to date. In particular, the case of a flat plate with coolant injection through thin slots and a flat plate, where coolant injection is provided by the flow transpiring from an underneath layer of distributed porosity, will be discussed. The simulations have been run on the Cray XC30 architecture of the UK supercomputer facility ARCHER using up to 3000-7000 cores. The full flowfield resolution by direct simulation is a challenging but at the same time novel approach in the hypersonic field, and for predicting the performance of wall cooling in high-temperature flow environments in particular.
