Gas turbine blades have previously been shown to corrode due to condensation of sulfide vapor on a cooled blade surface. In the present investigation, water vapor was condensed on a film cooled surface, simulating the condensation of sulfide vapor on a turbine blade. The injection section consisted of one row of holes (inner diameter of 1. 0 cm) inclined 30 degrees with the surface and inline with the main turbulent boundary layer flow. Experiments were carried out in a subsonic, zero pressure gradient, turbulent boundary layer with free stream velocities of 10. 5, 15. 75, and 21. 0 m/sec.
