| Popis: |
The flow field in the cross-flow separation region of an axisymmetric paraboloid at angles of attack of 40 and 50deg has been investigated experimentally by hot wire anemometer for the Reynolds numbers of 1.8×104 and 7.5×104 referred to the base diameter. The propagating process of turbulence in the separated vortices and the switching phenomenon of the flow have been clarified for each Reynolds number and angle of attack. The behavior of each vortex is estimated by calculating the skewness distribution of the velocity fluctuation. The difference of the process of vortex mergence for angles of attack has been identified. |
