Pseudo-shock waves and their interactions in high-speed intakes [PDF]
In an air-breathing engine the flow deceleration from supersonic to subsonic conditions takes places inside the isolator through a gradual compression consisting of a series of shock waves.

Servo-Stabilization of Low-Frequency Oscillations in a Liquid Bipropellant Rocket Motor [PDF]
The recent work of H. S. Tsien concerning the servostabilization of rocket motors is extended to the liquid bipropellant rocket motor. It is shown that by use of a feedback system containing a device to sense the combustion chamber pressure, a suitably ...

Transient combustion responses of homogeneous propellants to acoustic oscillations in axisymmetric rocket motors [PDF]
A numerical analysis of unsteady motions in solid rocket motors has been conducted. The formulation considers a 2-D axisymmetric combustion chamber and a choke nozzle, and treats the complete conservation equations accounting for turbulence closure ...

Effects of LOX Particle Diameter on Combustion Characteristics of a Gas-Liquid Pintle Rocket Engine
LOX/GCH4 pintle injector is suitable for variable-thrust liquid rocket engines. In order to provide a reference for the later design and experiments, three-dimensional numerical simulations with the Euler-Lagrange method were performed to study the ...

Oscillating flames in micro-combustion
New experimental results that demonstrate the existence of oscillating flames in micro-combustion are reported here. The results showed the presence of oscillating regimes with different behaviors in the transition between the stable flames, FREI (Flame with Repetitive Extinction and Ignition), and weak flames.

Physics of puffing and microexplosion of emulsion fuel droplets [PDF]
The physics of water-in-oil emulsion droplet microexplosion/puffing has been investigated using high-fidelity interface-capturing simulation. Varying the dispersed-phase (water) sub-droplet size/location and the initiation location of explosive boiling ...

Large-Scale Vortical Motion and Pressure Fluctuation in Noise-Controlled, Swirl-Stabilized Combustor
To clarify the mechanisms of combustion oscillation, combustion noise and their suppression by secondary fuel injection, simultaneous measurements of stereoscopic particle image velocimetry (SPIV) and pressure fluctuation in combustion chamber were ...
