Calculation Method for the Propulsive Jet and Its Aerodynamic Interaction with an Afterbody

摘要

A calculation method for single and multistream jet flows and their aerodynamic interaction with an afterbody is developed. The governing equations of viscous and inviscid flow fields are given in natural coordinates of the viscous flow. A transpiration mode takes into account the viscous inviscid interactions. Reynolds stresses and turbulent heat fluxes are calculated using kinetic energy, dissipation rate, and intermittency factor of turbulence. The calculation method is first applied on classical boundary layer flows, then verified by calculations of flows around afterbodies with single and two stream jets.
