An adverse effect of film cooling on the suction surface of a turbine vane [PDF]

open access: yes
Film-cooling-air ejection from the suction surface of a turbine vane was investigated. This investigation was conducted in a four-vane cascade on a J75 size turbine vane which had a row of holes near the leading edge. The experimental data are presented.
