RISEffects of Pressure and a Microporous Coating on HFC 245fa Pool Boiling Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study was conducted to experimentally characterize the pool boiling performance of hydrofluorocarbon HFC245fa at pressures ranging from 0.15 MPa to 1.1 MPa (reduced pressure range: 0.04–0.31). Pool boiling experiments ...
Pool Boiling Heat Transfer Characteristics of HFO 1234yf on Plain and Microporous Enhanced Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study characterizes the pool boiling performance of HFO1234yf (hydrofluoroolefin 2,3,3,3tetrafluoropropene). HFO1234yf is a new, environmentally friendly refrigerant likely to replace HFC134a in automotive airconditioning ...
Microstructured Surfaces for Single Phase Jet Impingement Heat Transfer Enhancement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation was conducted to examine the use of microstructured surfaces to enhance jet impingement heat transfer. Three microstructured surfaces were evaluated: a microfinned surface, a microporous ...
Automotive Silicon Carbide Power Module Cooling With a Novel Modular Manifold and Embedded Heat Sink
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The next generation of integrated power electronics packages will implement wide-bandgap devices with ultrahigh device heat fluxes. Although jet impingement has received attention for power electronics thermal management, ...
