Paper Abstract

A cold flow characterization and simulation of the turbine film cooling flows has been undertaken to assist analytical modeling of these flows for the calculation of heat transfer. Laser sheet lighting of the flow field, in which TiC14 vapor added to the film cooling flow reacts spontaneously with moist air in the channel flow to form TiO2, has been employed in the visualization. Illumination times of ten nano seconds were used the still photographs. The flows have been illuminated in planes parallel, perpendicular, and at 45° to the plane of film injection. The simulated turbine flows range through rho v ratios of .3 to 3.0. A film injection angle of 30° was used. Turbulence has been added to the free stream with a grid. The film flow interaction with two levels of free stream turbulence approaching are examined.
