Abstract

A series of heat transfer tests using a single pass slot shaped channel utilizing varying configurations of trapezoid shaped turbulence enhancement strip or varying configurations of high velocity jets issuing from side channels are studied. Thermochromatic Liquid Crystal techniques are used to determine local heat transfer coefficients, which are converted to normalized Nusselt values. The results show a marked improvement over traditional heat transfer enhancements used in the mid-span region of first stage turbine blades.
