Numerical solution of supersonic threedimensional freemixing flows using the parabolicelliptic NavierStokes equations
Abstract
A numerical method is presented for solving the parabolicelliptic NavierStokes equations. The solution procedure is applied to threedimensional supersonic laminar jet flow issuing parallel with a supersonic free stream. A coordinate transformation is introduced which maps the boundaries at infinity into a finite computational domain in order to eliminate difficulties associated with the imposition of freestream boundary conditions. Results are presented for an approximate circular jet, a square jet, varying aspect ratio rectangular jets, and interacting square jets. The solution behavior varies from axisymmetric to nearly twodimensional in character. For cases where comparisons of the present results with those obtained from shear layer calculations could be made, agreement was good.
