A Whole-Core Transient Thermal Hydraulic Model for Fluoride Salt-Cooled Reactors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermal hydraulic model is developed for a solid pin-fueled fluoride-salt-cooled small modular advanced high temperature reactor (SmAHTR). This preconceptual SmAHTR was developed by the Oak Ridge National Laboratory ...
Modeling of In Tube Condensation of Zeotropic Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Studies in the literature have shown that zeotropic mixture condensation rates are lower than those predicted using a purefluid approach. This has been attributed to the decrease in fluid temperature that occurs with ...
Effect of Temperature Difference on In-Tube Condensation Heat Transfer Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of temperature difference (Tsat − Tcoolant) on condensation heat transfer coefficients inside horizontal tubes is investigated in detail. Condensation experiments are conducted on propane inside a 7.75 mm ...
Status, Challenges, and Potential for Machine Learning in Understanding and Applying Heat Transfer Phenomena
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machine learning (ML) offers a variety of techniques to understand many complex problems in different fields. The field of heat transfer, and thermal systems in general, are governed by complicated sets of physics that can ...
Adsorption Beds: The Significance of Thermodynamic Properties and Particle Size on System-Level Heat Pump Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of an adsorption heat pump is a function of the equilibrium uptake and diffusion resistances of a particular system, which determines the refrigerant throughput during a cycle. Previous studies have sought ...
Experimental Investigation of Pressure Drop Characteristics of Viscous Fluid Flow Through Small Diameter Orifices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study on the flow of a highly viscous fluid through small diameter orifices was conducted. Pressure drops were measured for each of nine orifices, including orifices of nominal diameter 0.5, 1, and 3 mm and ...
A Simplified Thermal Hydraulic Model for Solid Pin-Fueled Molten Salt Reactors Under Low-Flow Accident Scenarios
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluoride-salt-cooled high-temperature reactors (FHRs) are an emerging category of next generation reactors. A thermal hydraulic modeling tool that can perform fluid flow and heat transfer analyses in the core region of the ...
Simple Mechanistically Consistent Formulation for Volume of Fluid Based Computations of Condensing Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerous investigations have been conducted to extend adiabatic liquid–gas volumeoffluid (VOF) flow solvers to include condensation phenomena by adding an energy equation and phasechange source terms. Some proposed ...
Falling Film Absorption Around Microchannel Tube Banks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation of heat and mass transfer in a fallingfilm absorber with microchannel tube arrays was conducted. Liquid ammonia–water solution flows in a fallingfilm mode around an array of small diameter ...
Visualization and Validation of Ejector Flow Field With Computational and First Principles Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Passive, heat actuated ejector pumps offer simple and energyefficient options for a variety of end uses with no electrical input or moving parts. In an effort to obtain insights into ejector flow phenomena and to evaluate ...
