A multi-zonal-marching integral method for 3D-boundary layer with viscous-inviscid interaction
Abstract
A curvilinear grid with an interacting inviscid solver is used to obtain a three-dimensional multi-zonal marching (MZM) solution for turbulence. Solutions are derived for the defect integral momentum equations, the local momentum equation at the outer edge of the entrainment zone, and the defect integral continuity equation. The MZM solution is generated in rectangular zones of the computing plane, accompanied by zonal sweep to account for zones degenerating into lines or overlapping zones. The second-order McCormack scheme solves the integrals at each step of the marching zonal sweep. A panel method without a vortex sheet is employed as the coupled inviscid solver to derive the wall transpirational velocity. The methods are useful for calculating skin frictions on the surfaces and edges of swept wings.
