Experimental Investigation on Flow Field Characteristics of Impinging-Film Cooling

Experimental Investigation into the Hydrodynamics Effects of Slot Film Cooling on a Cylindrical Model

An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...

Experimental Investigation of Impinging Axisymmetric Turbulent Fountains

The behaviour of a turbulent, axisymmetric, Boussinesq, vertical fountain that impinges on a horizontal plate a distance H from the fountain source is investigated. Images from Light Induced Fluorescence visualisation of the flow provide a clear picture of the internal structure of the impinging flow. The interaction between the impinging fountain and the plate results in a buoyant radial wall ...

An Experimental Investigation on the Flow Characteristics over Dimple Arrays Pertinent to Internal Cooling of Turbine Blades

Due to the dimple’s unique characteristics of comparatively low pressure loss penalty and good heat transfer enhancement performance, dimple provides a very desirable alternative internal cooling technique for gas turbine blades. In the present study, an experimental investigation was conducted to quantify the flow characteristics over staggered dimple arrays and to examine the vortex structure...
