An Assessment of Factors Affecting Prediction of Near-Field Development of a Subsonic VSTOL Jet in Cross-Flow.

Abstract

A three-dimensional parabolic Navier-Stokes numerical solution algorithm has been analyzed for prediction of the nearfield flow development of a VSTOL jet in subsonic crossflow. The essential aspects of algorithm definition, with regards to initial and boundary condition specifications, has been summarized. A momentum conserving pressure gradient computation has been developed to complete the problem definition and facilitate problem initialization. A sequence of overlapping interaction solutions has been evaluated for prediction of a circular jet at gamma = 8.0. The results of the 3DPNS predictions shave compared qualitatively with the sparse available experimental data. It is crucial that quality data be acquired to permit quantitative assessment of the results of this analysis procedure. (Author)
