RISCoupled Heat Transfer and Hydraulic Modeling of an Experimental Printed Circuit Heat Exchanger Using Finite Element Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Homogenized Heat Exchanger Thermohydraulic (HHXT) modeling environment has been developed to provide thermodynamic modeling of printed circuit heat exchangers (PCHEs). This finite element approach solves solid conduction ...
Investigation of Buoyancy Effects on Heat Transfer Characteristics of Supercritical Carbon Dioxide in Heating Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were performed to investigate the effects of buoyancy on heat transfer characteristics of supercritical carbon dioxide in heating mode. Turbulent flows with Reynolds numbers up to 60,000, at operating pressures ...
Batch Scale Hydrofluorination of Li27BeF4 to Support Molten Salt Reactor Development
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Li2BeF4, or flibe, is the primary candidate coolant for the fluoridesaltcooled hightemperature nuclear reactor (FHR). Kilogram quantities of pure flibe are required for repeatable corrosion tests of modern reactor materials. ...
Impact of Corrosion Test Container Material in Molten Fluorides
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of crucible material choice on alloy corrosion rates in immersion tests in molten LiF–NaF–KF (46.5–11.542 mol. %) salt held at 850 آ°C for 500 hrs are described. Four crucible materials were studied. ...
