Abstract
This paper investigates, both experimentally and analytically, the heat and fluid flow around the trailing edge of a film cooled gas turbine blade. In the analysis, steady state, two dimensional, incompressible, recirculating turbulent flow is considered. The momentum and energy equations are derived and transformed to the generalized format of Gosman and et al (2). The kinetic energy and dissipation term of turbulence (i.e. the k-E, model) is con sidered in the turbulence computational programs. Small number of empirical constants were obtained from both the mathematical model and the conducted experimental work. These mathematical constants provide the most realistic predictions of heat transfer coefficients, when compared with the available experimental data. 
The investigation considers varying Reynolds number in the range of 6.25 x 104 to 1.29 x 105. 
There is a satisfactory agreement between the present experimental and theoritecal results, for the blowing parameter (M = Uc/U ͚  ) in the range from zero to one.
