7. Mai 2024 · Algorithm 1 presents the overall steps to optimize the K value. First, a point cloud of film cooling holes is filtered. Then, an initial K value is set and the axial orientation of a film hole can be obtained. The extraction effect can be evaluated through the evaluation function \ (V\left (K\right)\).
8. Mai 2024 · Abstract. Various internal cooling techniques combined with external film cooling are applied to cool gas turbine blades, and the coolant extraction can cause variations in internal flow structures and cooling effectiveness. Effects of film extraction under different film hole diameters and coolant mass flow ratio on heat transfer ...
23. Mai 2024 · Two distinctive features are commonly observed in all fuel hole types: the rapid formation of a liquid film over a short distance from the Venturi nozzle and the generation of small droplets in the vicinity of the liquid film, along with their size distribution. The liquid film formed from the Venturi nozzle disintegrated into small ...
6. Mai 2024 · Abstract. For the design of modern gas turbine, cooling sources such as middle passage gap leakage flow, upstream slot leakage flow, and discrete film holes are designed to protect the blade. This research included middle passage gap leakage flow and two shapes of film holes (cylindrical holes and fan-shaped holes).
