Solar heat receiver is currently one of the important research topics of renewable energy. In present article, experimental measurements and numerical analyses are conducted to investigate the heat transfer performances of high temperature molten salt in spirally grooved solar receiver tube. The molten salt is used as a working medium to study the heat transfer coefficients of spirally grooved solar...
Based on elaborating the characteristics of capillary tube air-conditioning system, especially investigated the heat transfer property of this system cooling in summer, and establishes a two-dimensional mathematical model of steady-state heat transfer. In this paper, the Matlab program programmed by a micro-body heat balance method focuses the impact on the ceiling temperature field and the cooling...
The large-diameter flat serpentine finned tube is often used in direct air-cooled condensers. The distribution of the air velocities and the temperatures in the serpentine finned tube were analyzed by using three-dimensional numerical simulation methods. The heat transfer coefficients in finned tubes were obtained, which were subsequently used to fit the relational formulas of the heat transfer coefficients...
