Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

Results obtained previously by the discrete vortex method with a “viscous” correction are generalized. The boundaries of applicability of this method are determined. Previous results obtained for a flow past a flat plate are supplemented with solution convergence estimates. Exhaustion of a plane jet of a viscous incompressible fluid into the ambient space is modeled. The geometric parameters of the jet (its half-width, shapes of the streamwise velocity profiles, and intensity of oscillations) are analyzed. The calculated results are found to agree well with experimental data and with results calculated by other methods.
