Tip-to-Tail Scramjet Simulation with Plasma-Assisted Control
Abstract
A prominent pacing item in the quest for sustained hypersonic flight, and affordable access-to-space capability, is the development of an efficient air-breathing propulsion system. Key barriers of fluid dynamic origin includes, high thermal loads, shock/boundary layer interactions (SBLI) and fuel-air mixing at high-speeds, among other, all of which significantly degrade propulsion efficiency. One approach towards alleviating or eliminating these and other problems, and to provide a crucial energy management function, is to employ electromagnetic fields to control the relatively high temperature, low pressure environment encountered in proposed flight envelopes. To this end, several aspects of magnetogasdynamic (MGD) assisted scramjet flowpaths have been simulated using three-dimensional, integrated, multidisciplinary models requiring the large-scale resources available through the High Performance Computing Modernization Program (HPCMP). In this paper, we describe the complex flow field encountered in a scramjet and its control at various electromagnetic parameters.
