Investigation of Burnett Equations for Two-Dimensional Hypersonic Flow.

Abstract

Two separate investigations have been made: evaluation of various forms of Burnett equations for 2D flows including the frame dependent as well as frame independent forms; and exploration of the compatibility of Burnett equations with the second law of thermodynamics. Among eight different Burnett formulations investigated, six were found either to be impractical for 2D/3D computations, or to yield unphysical heat conduction. The remaining two forms yielded virtually identical numerical results, which led to an investigation that has revealed their previously unsuspected analytical identity. The frame dependence problem for Burnett equations is therefore not fully resolved. Detailed analysis of Burnett forms for the rate of irreversible production of entropy has demonstrated incompatibility with the second law of thermodynamics for certain flows. (AN)
