Numerical analysis of influence of flat plate diffuser parameters on performances of hot water storage tank

The thermocline hot water storage tank is the key equipment of large-scale solar central heating system, and the water distributor serves as the thermocline The layered hot water storage tank is an important component, and its structural parameters have an important impact on the thickness of the inclined temperature layer and the exergy efficiency in the tank. The number of openings, opening diameter, radius of the water distributor, and heat storage of the disc-type water distributor The influence of structural parameters such as the height-to-diameter ratio of the water tank on the heat

Regulation of visible-near infrared dual-band spectral radiative characteristics on biomimetic radiative cooling film

Radiant refrigeration is a zero-energy cooling technology with broad application prospects. However, most of the existing radiant refrigeration technologies Visible light transmission factors are not considered and cannot be applied to scenarios such as lighting buildings and photovoltaic cells. Based on the principle of spectral radiation control of beetle cutin, a method of using the refractive index difference of multi-layer films to achieve spectral radiation control is proposed to screen low-cost ITO and SiO2 , PDMS, etc. were used as base materials to construct an efficient and low-co

Molecular dynamics investigation of dissolution of carbon dioxide in methane

Pressurized liquefied natural gas (PLNG) technology can significantly improve the solubility of CO2 in LNG, but its microscopic process of dissolution and The mechanism has not yet been revealed. To this end, CO2 and methane were used as research objects, and molecular dynamics simulation methods were used to systematically study the changing rules and dissolution mechanisms of CO2 solubility in liquid methane at different temperatures. The results show that: the solubility of CO2 in liquid methane changes with It increases as the temperature rises, and the trend of increasing as the temper

Numerical simulation optimization of injection parameters by viscosity reducer flooding in Gaoqing heavy oil reservoir

The numerical simulation method was used to evaluate the application effect of viscosity reducer flooding in Gaoqing oil reservoir. Based on the indoor viscosity reducer evaluation test results, a numerical simulation model of viscosity reducer flooding was established, and the viscosity reducer injection parameters were determined based on the oil increase per ton of agent. Optimization. The results show that when the viscosity reducer mass concentration is 3000 mg/L, the injection rate is 200 m3/d, and a total of 0.2 VP (pore volume) of viscosity reducer is injected, the oil increase per

Division of volcanic eruption stages and distribution patterns of volcanic rocks in Yingcheng Formation of Xujiaweizi fault depression, Songliao Basin

Based on a large number of drilling cores, thin sections, well logs, isotope age and three-dimensional seismic data, the coal-bearing pyroclastic sedimentary interlayer of the Ying 2 Member was used as the standard layer, and the volcanic stratigraphic interface was identified through well log curves, combined with the Gd obtained from ECS logs. and Ti elements to identify the type of volcanic stratigraphic interface, and establish the "three sections and six phases" volcanic stratigraphic sequence of the Yingcheng Formation in the Xujiaweizi Fault Depression in the northern Songl
