Witryna7 cze 2016 · However, for wide-angled nozzles, internal shocks can be an inherent part of the flow from the nozzle and the bubbles which they produce are thus an inherent part of the impingement flow. From physical arguments concerning the main factors involved in producing a bubble, a parameter is constructed whose values are shown to be a … WitrynaThe shock generator is a wedge which is free to oscillate with a maximum flow deflection angle of 10 degrees. The frequencies chosen for the study includes 47 Hz, 80 Hz and 100 Hz. The incipient angle for the flow was calculated to be 4.7 degrees, which indicates that the flow separation of the boundary layer due to the shock …

WitrynaJet impingement is an effective method to cool equipment in high temperature environments, and has a wide range of future application prospects for cooling critical machinery structures, such as rocket launchers, turbine blades, modern electronics and com- pact heat exchangers [16]. Witryna3 paź 2024 · These flow impingement points increase local heat transfer coefficients, resulting in reduced total thermal resistance of the finless heat sink system. They confirmed that the proposed finless heat sink design achieved similar cooling performance to that of existing commercial state-of-the-art heat sinks under the same … Witryna15 gru 2024 · The flow and thermal behavior of impingement synthetic jet driven by sinusoidal and square signals were analyzed by Singh et al. .
