Abstract
The Reynolds-averaged Navier-Stokes equations, together with a two-layer turbulence model, have been solved to study the evolution of the near and far wake of elongated axisymmetric bodies, such as a prolate spheroid, with attached or separated flow at the tail. Supplemental calculation with the body in a circular duct were also performed to determine the effects of wind-tunnel blockage in the experiments. The results are examined in the light of experimental data and theories for turbulent near and far wakes. Is is found that the numerical solutions reproduce most of the essential features of the theory and experiments.
