Heat transfer coefficients on a flat plate surface downstream a row of simple and compound angle cylindrical holes are investigated using high-resolution thermographic liquid crystal technique. A variation of flow parameters including blowing ratio, and geometry parameters including compound angle and length-to-diameter ratio are examined. Blowing ratios (M) ranging from 0.3 to 2, length to diameter ratios (L/D) from 0.5 to 5, and two compound angle (beta: 0 degrees, 45 degrees) are employed composing a test matrix of 70 test cases. Detailed local, spanwise averaged, and area averaged heat transfer coefficients h(f)/h(0) are presented to illustrate the effect of length-to-diameter ratio and compound angle. The film cooling performance is also evaluated using NHFR method and Delta(phi) method by combining adiabatic film effectiveness and heat transfer coefficient data. Results indicate that Delta(phi) method has superiority in evaluating film cooling performance due to its direct reflection of temperature reduction by film protection. (C) 2018 Elsevier Ltd.
