Vorticity formulation for an actuated jet in crossflow
The mixing properties of a transverse jet are important to a variety of engineering applications. This study seeks to develop actuation strategies that manipulate the geometry and rate of mixing between jet and crossflow, based on a mechanistic understanding of vorticity structure and evolution. Previous studies have shown that vorticity from both the jet boundary layer and the channel wall bou...
متن کاملDirect Numerical Simulation of Jet in Crossflow actuators
Jet vortex generators have been proven to provide a mechanism to positively control boundary layer flows. The present paper illustrates a method to perform direct numerical simulations (DNS) of a jet actuator flow inside a laminar boundary layer. A structured finite difference method is used for the simulations. The numerical scheme was adapted to account for the large scale differences both in...
متن کاملDesign and Manufacturing of Jet to free Stream Simulator to Experimental Study of Interaction of Oblique Jet in Crossflow
The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...
متن کاملCharacteristics of Turbulent Nonpremixed Jet-flames and Jet-flames in Crossflow in Normal- and Low-gravity
It is well known that buoyancy has a major influence on the flow structure of turbulent nonpremixed jet flames. For example, previous studies have shown that transitional and turbulent jet flames exhibit flame lengths that are as much as a factor of two longer in microgravity than in normal gravity. The objective of this study is to extend these previous studies by investigating both mean and f...
