Investigation of Burnett Equations for Two-Dimensional Hypersonic Flow

Abstract

In 1935, D. Burnett developed a higher order set of constitutive stress relationships from a class of solutions to the Boltzman equations. Our research on Burnett equations has identified five basic scientific issues in need of resolution before really satisfactory computations of 2D (or 3D) flow fields can be made with these equations. These issues relate to (1) surface boundary conditions, (2) frame independence, (3) material derivative approximation, (4) positive-definite dissipation (?), and (5) upper altitude limit for applicability. This report describes progress in areas 1, 3, and 4, and also an investigation of the interaction of a thick oblique shock impinging on a cowl lip in high-altitude hypersonic flow.
