Measurements and analysis of high-intensity turbulent characteristics in a turbine-agitated tank

Turbulent flow in the impeller zone and the bulk zone in a turbine-agitated tank was measured by constant temperature anemometry. A split-film probe was used which sensed the directionality of the flow. Turbulent characteristics such as intensity and anisotropy were expressed by statistical moments for all three directions of flow. Turbulent kinetic energy and mean Reynolds stresses were also calculated. The convective velocity was estimated from Taylor's hypotheses as well as from other hypothesis and approximations which considered both the mean velocity and the fluctuations of the flow. The local energy dissipation rates were calculated using three different methods. They were based on energy dissipation spectrum. Kolmogorov's hypotheses and dimensional analysis. The method based on Kolmogorov's hypotheses is suggested here.
