Large eddy simulation of compound angle hole film cooling with hole length-to-diameter ratio and internal crossflow orientation effects

International Journal of Thermal Sciences, 2017
Abstract Compound angle hole film cooling with varying length-to-diameter ratio and internal crossflow orientations is investigated by large eddy simulation (LES). The film density ratio is 1.5, and the blowing ratio ranges from 0.4 to 1.2. The compound angle of 45° and three length-to-diameter ratios (L/D) from 0.5 to 5 are chosen for the ...

On the Flow Structures and Adiabatic Film Effectiveness for Simple and Compound Angle Hole With Varied Length-to-Diameter Ratio by Large Eddy Simulation and Pressure-Sensitive Paint Techniques

Journal of Heat Transfer, 2017
The effects of hole length-to-diameter ratio and compound angle on flat plate film cooling effectiveness are investigated from an experimental and numerical view. Film cooling effectiveness measurements are performed for seven blowing ratios (M) ranging from 0.3 to 2, five-hole length-to-diameter ratios (L/D) from 0.5 to 5, and two compound angles (β ...

Investigation of subcooled and saturated boiling heat transfer mechanisms, instabilities, and transient flow regime maps for large length-to-diameter ratio micro-channel heat sinks

International Journal of Heat and Mass Transfer, 2018
Abstract This study investigates the interfacial behavior and heat transfer mechanisms associated with flow boiling of R-134a in a micro-channel test module. The test module features 100 of 1 × 1 mm2 square micro-channels. Large length of micro-channels used (609.6 mm) is especially important to capturing broad axial variations of both flow and heat ...
