FLUID AMPLIFICATION. 6. AERODYNAMIC STUDIES OF FREE AND ATTACHED JETS,
Abstract
Theoretical and experimental investigations were conducted to provide information regarding the aerodynamic characteristics of two-dimensional turbulent compressible jets. The investigations included studies of free jets, wall jets, and reattaching jets. The theoretical investigations provided analytical models for the three types of jet flows, procedures for predicting the velocity profile development characteristics for free jets and wall jets and a procedure for predicting the reattachment location and mean pressure in the separation bubble for reattaching jets. The experimental studies which were conducted provided data to substantiate the analyses and to evaluate empirical constants. These data included measurements of the flow profiles at various stations downstream of the nozzle exit for the three types of jet flows. For the reattaching jets additional measurements were made of wall static pressure distributions, reattachment locations, and the pressure recovery and weight-flow characteristics of diffusion systems located downstream of the reattachment point.
