RISPredictions of Enhanced Heat Transfer of an Internal Blade Tip-Wall With Hemispherical Dimples or Protrusions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool ...
Comparisons of Pins/Dimples/Protrusions Cooling Concepts for a Turbine Blade Tip-Wall at High Reynolds Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The blade tip region encounters high thermal loads because of the hot gas leakage flows, and it must therefore be cooled to ensure a long durability and safe operation. A common way to cool ...
Analysis of Flow and Thermal Performance of a Water-Cooled Transversal Wavy Microchannel Heat Sink for Chip Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasing output power of the integrated circuit chips, the heat flux involved is being accordingly increased. In such situation, the air has almost reached its limit of cooling ...
Computational Analysis of Pin-Fin Arrays Effects on Internal Heat Transfer Enhancement of a Blade Tip Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cooling methods are strongly needed for the turbine blade tips to ensure a long durability and safe operation. Improving the internal convective cooling is therefore required to increase the ...
Mitigation of Heat Transfer Deterioration of Supercritical CO2 Vertical Tube Upward Flows by Introducing Truncated-Ribs in Helical-Like Distribution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To effectively alleviate the heat transfer deterioration (HTD) phenomenon of supercritical CO2 flow in a vertical circular tube, this paper proposes multiple truncated ribs from a whole O-ring rib but distributed in ...
