Behavior of wall jet in laminar-to-turbulent transition
Abstract
Reslts are presented concerning the linear stability analysis of an incompressible plane wall jet flow, i.e., flow tangent to a surface and interacting with a still fluid. The numerical solutions of the Orr-Sommerfeld equation are obtained by means of a finite-element approximation. Two different unstable modes are found and two neutral curves are plotted, which show an overlapping region of instability for both types of modes. Experimental flow is realized, and a visualization is compared with a computer-simulated flowfield.
