RISNumerical Investigations of a Single Loop Pulsating Heat Pipe for Cryogenic Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermohydraulics of a single-loop pulsating heat pipe (PHP) for cryogenic applications have been simulated. The 120 mm long PHP tube is made of a 1.5 mm diameter inner tube of thickness 0.83 mm. The computation fluid ...
Geometric Mean of Fin Efficiency and Effectiveness: A Parameter to Determine Optimum Length of Open-Cell Metal Foam Used as Extended Heat Transfer Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High porosity open-cell metal foams have captured the interest of thermal industry due to their high surface area density, low weight, and ability to create tortuous mixing of fluid. In this work, application of metal foams ...
Thermohydraulic Behavior of Minichannel Surface Simulated With Gaussian Function and Actual Roughness Data Generated Using Three-Dimensional Optical Surface Profilometer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of surface roughness on the thermohydraulics in minichannels has been studied numerically. Fluid flow (at low Reynolds number) through a typical three-dimensional (3D) channel subjected to constant heat flux (at ...
Experimental and Computational Evidence of Damped Axial Conduction With Reciprocating Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Axial conduction is a crucial performance deteriorating factor in miniaturized heat transfer devices, primarily due to the low fluid flow rates, high solid cross-sectional to free-flow area ratio, and use of high thermal ...
Nexus Between Human Thermoregulation and Cardiovascular Functions—A Preliminary Simulation for a Moderate Variation of Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Though the interaction between cardiovascular functions and thermoregulation is enormously complex yet immensely important, very little effort to date has been spent to simulate it from a system point of view. The present ...
