A gaskinetic model for background flow effects on rarefied jet flow
© 2017 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved. We report some work on studying interactions between rarefied background and jet flows by considering two problems. The first problem is about interactions between a background flow and a rarefied jet flow. For the first problem, the parameters describing the rarefied jet and background flow conditions are assumed known. Centerline results indicate that with background flows, jet flow properties may show quite different behaviors. The second problem is about how to determine the background and jet flow parameters with measured data. Several linearized equations are derived for the flowfield densities and number fluxes. The solving process includes initial estimations on the parameters for the rarefied jet and background flows, and iteration methods are used to determine these parameters. Test results indicate the procedure is accurate and efficient.
