Transactions of the Canadian Society for Mechanical Engineering, 1991
Measurements of the flow field and film cooling effectiveness downstream of a two-dimensional inclined slot were made. A two-dimensional numerical model solving the transport equations in curvilinear orthogonal coordinate system was developed to simulate film cooling process. Comparisons were made between numerical and experimental results.

Film Cooling Characteristic of Double-Fan-Shaped Film Cooling Holes
Volume 3: Heat Transfer, Parts A and B, 2009The film cooling performance downstream of a single row of double-fan-shaped film cooling holes in a flat plate have been investigated by experimental measurements and numerical simulation. The entrance and exit of double-fan-shaped holes are comprised of a lateral expansion of 15° from the original simple cylindrical shape with stream-wise inclination

Predictions of Adiabatic Film Cooling Effectiveness for Effusion Film Cooling
Volume 4: Turbo Expo 2007, Parts A and B, 2007This paper presents computational predictions of adiabatic film cooling effectiveness for effusion cooling systems with 90° and 30° holes. Predictions are performed for a range of coolant injection mass flow rates per unit surface area, G, of 0.1kg/sm2 - 1.6 kg/sm2 for 90° holes with constant pitch-to-diameter ratio of X/D = 11 and 10 rows of holes and

Adiabatic Film Cooling Effectiveness Measurements Throughout Multirow Film Cooling Arrays
Journal of Turbomachinery, 2017Adiabatic film cooling effectiveness measurements are obtained using pressure-sensitive paint (PSP) on a flat film cooled surface. The effects of blowing ratio and hole spacing are investigated for four multirow arrays comprised of eight rows containing 52 holes of 3.8 mm diameter with 20 deg inclination angles and hole length-to-diameter ratio of 11.2.
