Abstract:
Results of experimental and numerical investigations of the flow around an elongated axisymmetric body of revolution in a low-velocity wind tunnel with a closed test section and in a free flow are reported. The Reynolds number based on the body length is varied in the interval from 2.75⋅106 to 9.40⋅106. The problem is solved numerically under the assumption of an axisymmetric steady incompressible flow with the use of the ANSYS Fluent software. It is demonstrated that the test section walls produce a significant effect on the flow character and aerodynamic performances of the body of revolution for the case where the blockage factor of the test section by the body of revolution is formally within 2%.
