1 High Performance Computing in the SCRamjet Design Project HPC User Forum Meeting Roanoke, April /21/091 Chris Larson, Axel Dietrich

2 04/21/092 combustion occurs at supersonic speeds no moving parts no on-board oxidizer A Scramjet is an air-breathing propulsion system, developed to operate in the hypersonic region of flight Project Mission Goal is to design a flight-capable Scramjet engine

3 04/21/093 The design process incorporated different state of the art computer software

4 04/21/094 Flow properties throughout engine cycle determined using isentropic flow equations and STANJAN InletIsolatorCombustorNozzle T 01 P 01 T 02 P 02 T 03 P 03 T 04 P 04 T 05 P 05 T 1 P 1 T 5 P 5 Mach 5 Air Cavity, injection, torch Mach 2 STANJAN software used to model combustion process in Scramjet engine Combustor split into ten different sections, each in which hydrogen is injected, in order to more accurately model combustion process

5 Isolator 04/21/095 CAD models of Scramjet engine components developed using NX 6 Engine component geometries dependent on flow properties throughout Scramjet, and initial constraints on isolator and combustor inlet geometry Combustor Nozzle

6 CFD model has been generated in order to simulate the flow conditions in the combustor 04/21/09 6 Free Stream Model of the combustor containing the cavity CFD Model of the combustor section designed in GAMBIT 2.4

7 CFD simulation validated predicted combustor flow conditions exited by the Cavity 04/21/09 7 Distribution of mach number simulated by FLUENT 6.3

8 CFD simulation validated predicted combustor flow conditions exited by the Cavity 04/21/09 8 Distribution of static temperature simulated by FLUENT 6.3

9 04/21/099 To simulate wind tunnel testing conditions, a more detailed CFD simulation was started Insert plate that will be used for wind tunnel testing GAMBIT model of insert plate GAMBIT model was divided into 9 sections to apply different types of meshes
