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 ...
Protection Measures against Mine Subsidence Taken at a Building Site
Publisher: American Society of Civil Engineers
Abstract: With little mining information, old abandoned coal workings were grouted beneath a proposed building site. Mine stabilization was found necessary after an investigation of subsidence potential was performed. The investigation ...
