heat transfer coefficientnumerical simulationinverse problemIn the steam generator of a sodium-cooled fast reactor, high-pressure water flows inside heat transfer tubes while liquid sodium flows on the shell side. Heat is exchanged through the tube wall. When the tube fails, water vapor leaks into...
Remember that the heat transfer coefficient is defined as the amount of heat that is transferred from/to a unit area per unit time when the temperature difference between the surface and the ambient is one degree. From: Comprehensive Energy Systems, 2018 ...
Heat transfer coefficientSmooth tubeEnhanced tubeANNIn this study, experiments were conducted for the flow of R-134a condensing in an enhanced inclined tube at a saturation condensing temperature of 40 °C. The enhanced tube had a helix angle of 14° with a mean internal diameter of 8.71 mm....
Heat transfer coefficientFlow patternsThe purpose of this study was to present the heat transfer coefficients and flow patterns during the condensation of R134a inside an inclined smooth tube at low mass fluxes and different temperature differences (the temperature differences were between the saturation...
A reasonable heat transfer coefficient correlation for a finned-tube air cooler was established by applying the methods of dimensional analysis and function analysis. This approach focused on an air cooler design in which the refrigerant phase changes in the tube. A pump-feeding ammonia air cooler ...
The objective of this experimental study is to evaluate the heat transfer coefficient outside a tube with annular transverse fins, derived from strips of copper mechanically bound and coupled outside. Water is used as the heating medium, in turbulent conditions and flowing at different temperatures ...
Advantages: high heat transfer coefficient, compact structure and detachable structure. Disadvantages: small processing capacity, low operating pressure, less than 1.5 Mpa, operating temperature can not be too high. 3. Fin Heat Exchanger (1) Finned-tube heat exchanger ...
The paper presents a research on the heat-transfer coefficient at the surface of a sprinkled tube bundle, using a boiling simulation. A tube bundle consists of thirteen copper tubes divided into two rows and it is located in a low-pressure chamber where vacuum is generated by an exhauster vi...
