RISExperimental Investigation of Jet Impingement Cooling With Carbon Dioxide at Supercritical Pressures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Jet impingement cooling is widely used in many industrial applications due to its high heat transfer capability and is an option for advanced high power density systems. Jet impingement cooling with supercritical pressure ...
Experimental Study on Combined Cooling Method for Porous Struts in Supersonic Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A combined transpiration and opposing jet cooling method was experimentally investigated for protecting porous struts with microslits in the leading edge. Schlieren images showed that this cooling method significantly ...
Modeling and Performance Analysis on an Integrated System Combining Supercritical Carbon Dioxide Brayton Cycle With Leakage Feedback Utilizing a Heat Pump or Direct Compression
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: CO2 leakage due to the coexistence of pressure differentials and clearances within the integrated turbine-alternator-compressor (TAC) of the kW-level sCO2 Brayton cycle is a key issue affecting cycle efficiency and long-term ...
Phenomenon and Mechanism of Spray Cooling on Nanowire Arrayed and Hybrid Micro/Nanostructured Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Enhancing spray cooling with surface structures is a common, effective approach for high heat flux thermal management to guarantee the reliability of many high-power, high-speed electronics and to improve the efficiency ...
