Rope Project

The major accomplishment of this task, to date, was the successful implementation, of a turbulence modeling theory into the previous laminar near wake code. First results were obtained, and are be presented on a 6 deg half angle adiabatic cone at Mach 7.5 and freestream Reynolds number 1,700,000, based on base diameter. These calculations represent the beginning of the portion of the analysis directed towards improving and verifying the implemented turbulence modeling theory for the wake problem. This is a crucial part of the analysis of the turbulent near wake, since the eventual goal of the present task is to apply the modeling to reentry vehicles under conditions in which no detailed flowfield and turbulence measurements have been made. Other planned tests of the theory will be subsequently discussed, but first an outline of the theory and a discussion of the new results will follow.
