Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.
Experimental studies of single slot jet impinging upon a
concave surface are conducted by classical Particle Image
Velocimetry (PIV) and infrared thermography, with nozzle exit
Reynolds number (Re = 3200), dimensionless impinging height
(H/b = 3 & 7) and relative curvature of the wall (Dc/b = 5).
Results indicate that the oscillatory impinging jet generated a
uniform and symmetric heat transfer area while the stabilized
impinging jet caused an asymmetric heat transfer. This type of
jet may be controlled by changing the outlet condition.
