This book was released on 1968 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of an experimental and theoretical investigation of the near wake in an axisymmetric flow past a slender body at Mach number 3.92 with and without base injection are presented. For the experimental part centerline distributions of pressure, temperature, Mach number, velocity, and concentration were obtained. Turbulent as well as laminar flow fields were investigated for the zero injection case. Base injection problem was studied only in the turbulent flow case using gaseous hydrogen, helium, nitrogen, and argon as injectants. A special effort was made to study the variation of pressure, velocity, and Mach number at the base with base injection. For the theoretical part an expression was developed to calculate the centerline distribution of turbulent viscosity from experimental profiles using full Navier-Stokes equations; flow fields with non-zero pressure gradients were considered. Using this expression, centerline viscosity distributions for various cases of wake flow and coaxial mixing were calculated and the results compared with those obtained from the empirical models.

Available in PDF, EPUB and Kindle. Book excerpt: An analytical model for planar and axisymmetric, supersonic, turbulent, near-wake flows is presented. The viscous region behind the blunt base is described by the integral form of the boundary-layer equations, and the inviscid outer-flow region, including the remnant of the initial turbulent boundary layer, is computed with the rotational method of characteristics. The solution of the two regions is fully coupled. The saddle-point singularity, similar to the Crocco-Lees critical point, occurs downstream of the rear stagnation point. The base pressure is obtained by iteration of the initial conditions until the flow-field solution will pass through the singularity. Base bleed of a gas different from the outer-stream gas is included in the formulation, and provision is made to treat equilibrium chemical reactions in the viscous wake. However, an unresolved problem has been encountered in the solution of the species conservation equations. Therefore, results for only single gas flows are presented. The analytical model is shown to adequately predict the effect of free-stream Mach number and initial boundary layer on the planar base pressure. In addition, the planar flow-field structure is well predicted. Axisymmetric base pressure and flow-field structure are reasonably well predicted for free-stream Mach numbers greater than 2.0, but the turbulent transport model used yields only fair results for Mach numbers less than 1.7. The effect of base bleed on the axisymmetric base pressure is well predicted. (Author).
