Unsteady Structure and Development of a Row of Impingement Jets, Including Kelvin–Helmholtz Vortex Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Considered is a cylinder channel with a single row of ten aligned impinging jets, with exit flow in the axial direction at one end of the channel. For the present predictions, an unsteady ReynoldsAveraged Navier–Stokes ...
Numerical Analysis of Flow Structure and Heat Transfer Characteristics in Dimpled Channels With Secondary Protrusions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dimple structure is an effective heat transfer augmentation approach on coolant channel due to its advantage on pressure penalty. The implication of secondary protrusion, which indicates protrusion with smaller dimension ...
Conjugate Heat Transfer Evaluation of Turbine Blade Leading-Edge Swirl and Jet Impingement Cooling With Particulate Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Internal cooling structures for gas turbine engines are becoming more complicated to push the hot gas temperature as high as possible, which, however, allows particulates drawn into the coolant air to be more readily to ...
Effect of Reynolds Number, Hole Patterns, and Hole Inclination on Cooling Performance of an Impinging Jet Array—Part I: Convective Heat Transfer Results and Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study comprehensively illustrates the effect of Reynolds number, hole spacing, jet-to-target distance, and hole inclination on the convective heat transfer performance of an impinging jet array. Spatially resolved ...
Double Wall Cooling of an Effusion Plate With Simultaneous Cross Flow and Impingement Jet Array Internal Cooling
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Considered is double wall cooling, with full-coverage effusion-cooling on the hot side of the effusion plate, and a combination of impingement cooling and cross flow cooling, employed together on the cold side of the ...
Louver Slot Cooling and Full-Coverage Film Cooling With a Combination Internal Coolant Supply
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Within the present investigation, a louver slot is employed upstream of an array full-coverage film cooling holes. Cooling air is supplied using a combination arrangement, with cross-flow and impingement together. The ...
Particulate Deposition Effects on Internal Swirl Cooling of Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particulate deposition effects on flow and heat transfer in an internal swirl tube subjected to fly ash ingestion were investigated by constructing an unsteady simulation framework, in which a particle–wall interaction ...
