Stability of free shear layer
Abstract
A twodimensional flow behind a splitter plate is solved using a numerical technique. Free shear layer is formed behind a splitter plate, when velocity difference is present upstream of the plate. An approach is attempted to observe the behaviors and stability of the flow. The flow properties are checked from a number of viewpoints, in order to see whether the numerical scheme and the calculated results are appropriate to express the real flowfield: the vortex pairing, the critical Reynolds number, the effect of viscosity, the distribution of Reynolds stresses, etc. As a result, most of the important flow phenomena are both qualitatively and quantitatively reproduced in the solution at the Reynolds number lower than 10,000.
