What is Generation of Longitudinal Vortices in Internal Flows with an Inclined Impinging Jet and Enhancement of Target Plate Heat Transfer about?

Flow velocity measurements and heat transfer experiments were carried out for a jet obliquely discharged into a cross ̄ow in a duct. The ̄ow measurements were made with optical ®ber laser Doppler velocimetry, and the heat transfer experiments were made by making use of a thermochromic liquid crystal. The obtained velocity data reveal that the inclined jet is eective in generating longitudinal vortices in the cross ̄ow. It is demonstrated that the longitudinal vortices are eective in enhancing target plate jet impingement heat transfer. It is, therefore, promising as a means to eectively cool inner surfaces of high temperature gas turbine vanes. The obtained heat transfer data are discussed in detail in comparison with the measured ̄ow ®eld and turbulence data.
