Abstract
The main objectives of this paper are to report and compare experimental and theoretical results for flow behind an axi-symmetrical baffle; and to assess the capability of the k ∼ ɛ model of turbulence to predict recirculating flows. For the theoretical work, a finite-difference procedure was used. The turbulence model employed for the prediction involved the solution of two differential equations; one for the kinetic energy of turbulence k and the other for its dissipation rate ɛ. Experiments were conducted in a wind tunnel by way of a five-hole pitot sphere. Agreement between the experimental data and the prediction is satisfactory
