Effects of Key Inlet Design Parameters on the Performance of Supplementary Combustion Nozzle [PDF]
Journal of Applied Fluid MechanicsSolid rocket motors (SRMs) have limited propulsion performance due to their short fuel combustion duration and low specific impulse. The supplementary combustion nozzle (SCN) injects air into the nozzle expansion section to promote secondary combustion ...

Design and fabrication requirements for low noise supersonic/hypersonic wind tunnels [PDF]
A schematic diagram of the new proposed Supersonic Low Disturbance Tunnel (SLDT) is shown. Large width two dimensional rapid expansion nozzles guarantee wide quiet test cores that are well suited for testing models at large angle of attack and for swept ...

Impact of Lens Angle and Nozzle Geometry on Aerodynamic Focusing: A Numerical Study
AtmosphereStraight-edge thin plate orifices (90° half-angle) are used as the focusing elements in most aerodynamic lenses. They are simple to fabricate and have fewer boundary-layer effects as compared to other geometries, such as capillaries and converging and ...

Modern developments in shear flow control with swirl [PDF]
Passive and active control of swirling turbulent jets is experimentally investigated. Initial swirl distribution is shown to dominate the free jet evolution in the passive mode.
