Zonal Models For Incompressible Flows.
Abstract
A successful Unified Zonal model has been created for the entire class of free-shear flows (wakes, jets, and mixing layer) by S. Tzuoo working with J. H. Kline. Results check data within 10% for all well-documented cases including the near and far fields and planar and axisymmetric cases. Programs run in a few minutes in a VAX. The solution provides, for the first time, a sufficient set of non-dimensional governing parameters for the entire class of flows and thus provides both a single model and improved understanding of the physics of free-shear flows. As a class for flows, free shear flows are important in jet engines, combustion systems, separated flows and many other applications. Adequate solutions for the near field of any of these flows has not been available previously even though most applications are in the near field region. Consideration of the processes used suggests that the zonal methods developed will generalize successfully to many other flow types.
