  • Effects of Nozzle Geometry on Turbulent Characteristics ...

    2019-6-29 · The effects of nozzle exit geometry on the characteristics of a surface attaching jet were investigated experimentally. Three different types of nozzle geometries were studied, including a circular, square and rectangular nozzle with the same exit area. The jets were discharged with an offset height of two nozzle width at a Reynolds number of 5500.

    2020-9-1 · This was due to the effect of secondary hole in mitigating the primary hole vortex. Sun et al. compared the performance of a double jet hole with other geometries by keeping the exit area same for all configurations. The sister hole for the double jet had a compound angle of γ = 30°and α = 30°. The coolant jets from the holes formed a complex vortex structure and forced the coolant to adhere to the …
