Numerical Investigation of a Jet and Vortex Actuator (JaVA)

In the present study an active flow control actuator is studied numerically using the CFD package Fluent R ©. A two-dimensional setup is chosen which corresponds to a cut through the actual configuration that was studied experimentally by Lachowicz et al. [1] and called “Jet and Vortex Actuator” (JaVA) because of its ability to produce such completely different flow regimes when its actuation f...

Quantitative experimental and numerical investigation of a vortex ring impinging on a wall

A joint experimental and computational methodology is developed and applied to investigate a vortex ring impinging normally on a wall. The method uses digital particle image velocimetry to make planar flow measurements, which are then used to initialize a second-order finite difference calculation. The experiment and the simulation are compared at later times and agree extremely well. The ring ...

Draft Gt2003-38118 Experimental and Numerical Investigation of Impingement on a Rib-roughened Leading-edge Wall

Leading edge cooling cavities in modern gas turbine airfoils play an important role in maintaining the leading edge temperature at levels consistent with airfoil design life. These cavities often have a complex cross-sectional shape to be compatible with the external contour of the blade at the leading edge. Furthermore, to enhance the heat transfer coefficient in these cavities, they are often...
