The dynamic characteristics of flywheel energy storage system have been studied extensively in recent years. A single point flexible support is suitable for the small f... Thermodynamic analyses of the solar-driven Kalina cycle having a variable con...   　　Solar thermal power generation is currently an attractive solar electricity technology. Currently, we face an important issue of lower annual solar-to-power efficiency (approximately 10.0%) using parabolic trough technology because the direct normal irradiance instantly varies, and the solar thermal power cycle... Investigation on axial effect of slot casing treatment in a transonic compressor   　　This paper reports the effect of the axial position of the slot casing treatment on the performance of transonic compressor NASA Rotor 67 by unsteady numerical simulation. The interaction of the recirculation in the slots and flow near the blade tip is analyzed to understand the flow mechanisms. The relative im... Technical and economic feasibility of the Isopropanol-Acetone-Hydrogen chemic...   　　Chemical heat pump is promising alternatives in waste heat recovery applications. The present paper focuses on the technical and economic feasibility analysis of the Isopropanol-Acetone-Hydrogen Chemical Heat Pump (IAH-CHP) system. A small scale prototype of the IAH-CHP was established. Coefficient of performan... Pore-scale investigation of effects of heterogeneity on CO2 geological storag...   　　The geological sequestration of CO2 is considered to have great potential. However, the heterogeneity that characterizes most geological reservoirs significantly affects the migration, trapping, and leakage of CO2. The present study involved a pore-scale investigation of the effects of heterogeneity in pore siz... An innovative solar-powered absorption refrigeration system combined with liq...   　　Air-conditioning and fresh water are increasingly required in civilian and industrial sectors; however, conventional technologies are generally individual systems and consume substantial electric power. This paper proposes a new solar-powered double-product system for cooling and water based on the absorption r... Experimental Investigation on the Thermal-Energy Storage Characteristics of t...   　　This paper first proposes the concept of using subcritical water as a thermal energy storage (TES) material. Subcritical water has a maximum TES temperature of 330°C and an internal energy storage density as high as 977.75 MJ/m3, which is very suitable for industrial waste heat recovery. This paper investigate... The heat transfer mechanism study of three-tank latent heat storage system ba...   　　A three-tank latent heat storage system in which liquid lead–bismuth eutectic alloy (LBE) is used as sen-sible heat storage medium, and sodium nitrate is selected as the phase change material (PCM), is proposed in the present work. The performance of thermal storage system depends chiefly upon the heat transfe... Numerical investigation of room temperature magnetic refrigerator using micro...   　　The paper reports numerical investigation of room temperature, active magnetocaloric regeneration (AMR)refrigerators/heat pumps using microchannel regenerator. The microchannel regenerators are made of a magnetocaloric material (MCM), Gd, with diameter of the circular channels ranging from 0.7 mm to 2.0 mm. Wat... Mathematical modeling and thermal-hydrodynamic analysis of vertical water wal...   　　In this study, a mathematical model for a 660MW SCFB boiler design with annular furnace was deduced and thermal–hydrodynamic analysis was performed to improve the design and operation of water wall. Based on the water wall structure and heat flux distribution of the SCFB boiler, the connection style, pressure ...   14 Page(s)   FirstPrev12345NextFinal
