Pressure-gain combustion has gained attention for airbreathing ramjet engine applications owing to its better thermodynamic efficiency and fuel consumption rate. In contrast with traditional detonation induced by a single wedge, the present study considers oblique shock interactions attached double wedges in hypersonic combustible flow. The temperature/pressure increases sharply across interact...

Hypersonic air breathing propulsion system has been in the minds of human being for a very long time. Ramjet propulsion provides efficient operation along with very high specific thrust and is very attractive for gun launch ramjet projectiles, hypersonic cruise vehicles and hypervelocity missiles. In the present investigation, Zr based fuel rich propellants in NC-NG matrix and HTPB matrix were ...

LA-UR-08-1690 30 Associate Directorate for Theory, Simulation, and Computation (ADTSC) LA-UR-09-01756 Understanding the nature of compressible turbulence is of fundamental importance in many applications ranging from astrophysics to combustion and aerospace engineering. Highly compressible turbulence is now thought to control star formation in dense molecular clouds [1]. The ability to paramete...

Continuous combustion processes are prominently encountered in many applications related to power generation, heating and propulsion. Examples include domestic and industrial burners, steam and gas turbines, waste generators, and jet and ramjet engines. Continuous combustion processes exhibit a wide range of dynamics. Of these, conditions which promote coupling with the acoustic field and resul...
