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 1 2 3 4 5 6 7 8 9 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
