Jet Fluid Mixing Control Through Manipulation Jet Fluid Mixing Control Through Manipulation of Inviscid Flow Structures
Rapid mixing is crucial for the efficient and environment-friendly operation of many industrial and propulsion devices involving jet flows. In this dissertation, two methodologies, self-excited nozzles and radially lobed nozzles, are studied and presented in order to enhance mixing in the near …

Wall-Jet Turbulence and Mixing Control by Way of a Pulsed Inlet Velocity
<p>Understanding wall-jet-induced turbulence and mixing is an important challenge in modern engineering, as drag reduction and mixing enhancement are attainable by modifying the flow development. Simulations are performed to investigate the effect on skin friction and flow mixing due to introducing …

Quantitative Acetone PLIF Measurements of Jet Mixing with Synthetic Jet Actuators
Fuel-air mixing enhancement in axisymmetric jets using an array of synthetic jet actuators around the perimeter of the flows (primarily parallel to the flow axis) was investigated using planar laser-induced fluorescence of acetone. The synthetic jets are a promising new mixing control and …

Oscillating shock impingement on low-angle gas injection into a supersonic flow
… into a supersonic airflow. Information on mixing, penetration, total pressure loss and turbulence structure from these experiments was used to estimate mixing control achieved by adding an oscillating shock to the helium injection flow field. Tests were conducted at Mach 3.0, with a total …
