RISComputational Analysis of Air/Mist Film Cooling Using a Sweeping Jet Fluidic Oscillator–Part I: Sweeping Air-Only Jet With Detailed Analysis of Vortex Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The sweeping jet can be a promising candidate in film cooling applications since it has a large lateral jet spreading which can be considered an advantage when compared to the regular steady jet film cooling. Fluidic ...
Computational Analysis of Air/Mist Film Cooling Using A Sweeping Jet Fluidic Oscillator–Part II: Sweeping Mist Jets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An ongoing research effort has been conducted for years to investigate the feasibility of mixing the air with mist (micron-level water droplets) to enhance heat transfer. It becomes very interesting to investigate how these ...
An Experimental Investigation of Sweeping Air/Mist Jet Film Cooling Through a Row of Passive Fluidic Oscillators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sweeping jet fluidic oscillators can be a promising candidate in film cooling applications since they have a large lateral jet spreading with more uniform cooling, which can be considered an advantage when compared to the ...
Validation of a Two-Phase CFD Air/Mist Film Cooling Model With Experimental Details—Part I: Development of an Experimental Test Facility
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film cooling is a cooling technique widely used in high-performance gas turbines to protect the turbine airfoils from being damaged by hot flue gases. Motivated by the need to further improve the turbine hot section cooling ...
Investigation of Thermal-Flow Behavior and Droplet Dynamics of Mist Sweeping Impinging Jet Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a 2-D numerical study to investigate the fluid flow behavior and cooling characteristics caused by injecting tiny water droplets into the sweeping air jet through a fluidic oscillator. An unsteady ...
