Abstract The inverted Brayton cycle can be applied to exploit the exergy content of the waste heat. The cycle can be operational at low heat source temperatures, and it is particularly suitable for recovering the low-temperature waste heat. Being low temperature-driven, the thermal efficiency of such an inverted Brayton cycle is considerably low. In this study, an attempt has been made to improve the performance of the cycle by hybridizing with an indirect evaporative cooling (IEC) device. A cou...

Abstract In order to predict the heat transfer coefficient between the immersed horizontal tube bundles and the pressurized fluidized bed, different types of heat transfer models research process for the horizontal tube surface are presented. The accuracy of these models has been analyzed with the data of pressurized experiments, which indicates the limitation of these models in the application of pressurized fluidized bed. A new semi-empirical emulsion renewal model is proposed which takes the ...

Abstract Coal fired power plant (CFPP) contributes to a huge fraction of CO2 emitted to the atmosphere in China. The Calcium Looping (CaL) technology may be the most promising and appropriate for post-combustion CO2 capture from CFPP. Two integration schemes, baseline case and redesigned case, which integrate CaL process into CFPP for CO2 capture, are presented in this manuscript aimed to reduce not only capture cost but efficiency penalty. The thermodynamic performances of integration schemes a...

Abstract Thermal energy storage (TES) is a broad-based technology for reducing CO2 emissions and advancing concentrating solar, fossil, and nuclear power through improvements in efficiency and economics. Phase change materials (PCMs) are of interest as TES media because of their ability to store large amounts of heat in relatively small volumes. The volume expansion during a phase change, typically between a solid and liquid, can cause breakage of protective coatings. This effort reports on the ...
Abstract In this study, a new heat transfer fins design, which may improve melting in thermal energy storage, is proposed. First, the melting process in the thermal energy storage without fins is discussed. Then, heat transfer fins are designed to allow the melting of the non-melting regions in TES. These fins are compared with the most widely used fin types in the literature. Melting processes of Base and Nano PCMs with different heat transfer fins are also investigated. The results showed that...

Abstract To absorb more renewable energy generation into power grid, once-through boiler-turbine (OTBT) units are usually required to operate in a wide load range while maintaining high safety and efficiency. Superheated steam temperature (SST), adjusted by spray water and feedwater together, plays a critical role on operational safety and economy. However, the models of OTBT units in existing literature haven’t reflected this essential interrelation, which may deteriorate control performances o...

Abstract In this work, eight different spiral woven mesh (SWM) structures, namely, SA, SB, SC, SD, SE, SF, SG and SH, were designed to investigate the effect of the SWM weaving method on the heat transfer performance of ultra-thin heat pipes (UTHPs). The SA and SH were SWMs, severed as the control group, and they were woven using only 0.05 and 0.04 mm diameter copper wires, respectively. The other six types were hybrid SWM (HSWM) structures that were woven from the two diameters copper wires. Th...

Abstract The supercritical heat transfer processes of n-decane during pyrolysis in rectangular tubes having three different equivalent diameters are studied numerically. The effects of mass flow rate (2–5 g/s), heat flux (109–436 kW/m2), and three different channel configurations having the same cross-sectional areas on the supercritical heat transfer characteristics of n-decane during pyrolysis are investigated. The heat transfer mechanisms are analysed from the perspective of pyrolysis, thermo...

Abstract With progress in technology and miniaturization of electronic devices, liquid coolants were used increasingly in personal computers, laptops, servers, and supercomputers. Micro heat sinks are widely used for cooling rate enhancement. Geometrical design plays a crucial role in the thermal performance of microchannel heat sinks. This work reviews the researches concerning micro heat sinks via three aspects: (1) Flow passage patterns, (2) Geometry of cross-sections (3) Inlet and outlet man...
Abstract Fluid transport and mixing analysis is performed numerically in micro/nano-channels, where the channel walls are fabricated with separated charged blocks. Two different streams of miscible fluids with different concentrations are supplied through the inlet port with an external applied electric field. The fluid is flowing under low Reynolds numbers experiences convection and diffusion effects which promote the desired mixing. In this paper theory of dynamic equations are used for the ti...
