RISVisualization of an Oscillating Heat Pipe with Hydraulic Diameter Far Exceeding the Conventional Maximum Hydraulic Diameter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For an oscillating heat pipe (OHP), the hydraulic diameter must be sufficiently small so that vapor plug and liquid slug can be formed by the capillary action. Therefore, the hydraulic diameter should not exceed a critical ...
Study on Forced Convective Heat Transfer of FC-72 in Vertical Small Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation of the forced convective heat transfer of FC-72 in vertical tubes at various velocities, inlet temperatures, and tube sizes. Exponentially escalating heat inputs were ...
Wettability Control of VACNT Array through Atmospheric Plasma Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wetting characteristics of the vertically aligned carbon nanotube (VACNT) array surface can be modified by atmospheric plasma treatment with masks. The plasma treatment of the VACNT array surface was performed by moving ...
Investigation on Carbon Nanotubes as Thermal Interface Material Bonded With Liquid Metal Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vertically aligned carbon nanotube (VACNT) films with high thermal conductance and mechanical compliance offer an attractive combination of properties for thermal interface applications. In current work, VACNT films ...
An Experimental Investigation of the Heat Transfer Performance of an Oscillating Heat Pipe With Copper Oxide (CuO) Microstructure Layer on the Inner Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an experimental investigation of whether heat transfer performance in an oscillating heat pipe (OHP) would improve if the inner surface of the heat pipe was coated with a layer of copper oxide (CuO). ...
Thermal Performance of Liquid Metal Alloy with Graphene Addition as Thermal Interface Material
Publisher: The American Society of Mechanical Engineers (ASME)

Abstract: In order to understand the heat transfer performance, startup, and fluid flow conditions of oscillating heat pipes (OHPs) with a hydraulic diameter far exceeding the maximum hydraulic diameter (MHD) defined by dh,max≤2σB ...
Thin-Film Evaporation Heat Transfer of Liquid Nitrogen and Its Application in Cell Vitrification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cell vitrification has been an important method of cell cryopreservation. The faster the cooling rate is, the higher the cell survival rate is. However, in conventional cell vitrification methods, film boiling forms a ...
Heat Transfer Analysis of Flash Evaporation With MEPCM
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Several seawater desalination technologies have been developed and widely used during the last four decades. In the current investigation, a new approach to the seawater desalination process is presented, which utilizes ...
