Manipulation of the Mixing Process between Streams of Different Velocity and Temperature in the Presence of Pressure Gradient.
Abstract
The aim of this phase of the project was to create a tool for linking the flow-pictures of the disturbed two-dimensional mixing-layer and the phase-locked averaged data calculated form experimentally measured velocity signals. We could thus relate the quantitative analysis of our experimental data to the visually observed phenomena. Of particular interest is the presence of a pairing process of vortices in the experimental data. There are two theoretical approaches to deal with the mixing-layer type of flow. One is based upon stability theory, and the other tries to solve the basic flow equations by various mathematical models. This report compares both the longitudinal and lateral velocity components, as well as the vorticity distribution, using the multiple-scales expansion method. Simultaneous measurements of two velocity components formed the experimental basis for this comparison.
