Abstract Distributed renewable energy supply (RES) is a new pattern for the transformation of power grids. As characteristic case RES, microgrids have an advantage in convenient operation. However, management remains as major concern. With emergence decentralized paradigm, blockchain potentially provides reliable data metering and payment whole life cycle management. In particular, demand response (DR) microgrid can stimulate demanders to spontaneously manage their load consumption maintain...
An optimal prediction model for flow boiling heat transfer of refrigerant mixture R245fa inside horizontal smooth tubes is proposed based on the GRNN neural network. The main factors strongly affecting such as mass flux rate ( G ), q quality vapor‐liquid x evaporation temperature T ev and tube inner diameter D ) are used inputs coefficient h output. Neural network to optimize in light pipe through training learning. results good agreement with experimental results. For transfer, average...
The Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method is used find optimal mixing scheme of Zhaotong lignite, Fuyuan bituminous coal, and Xiaolongtan lignite in terms combustion performance. Comparative evaluation different schemes also conducted, where the flammability index, comprehensive characteristic burnout temperature, economic costs can be measure advantages disadvantages with parameters. Through analysis optimization, it found that when Xiaolongtan,...
In the process of bottom blowing bath smelting, continuous bubbles are formed and rise in melt after gas is ejected. order to reveal motion behavior wake characteristics during injection process, rising coaxial double studied through numerical simulation, velocity deformation obtained. Based on vortex identification reconstruction flow field, formation, evolution, configuration bubble The results show that terms characteristics, aspect ratio upper always less than 1, lower has a large span...
Abstract In the design and optimization of nanofluids, it is crucial to investigate characterize thermal conductivity enhancement mechanisms their influencing factors. Although effect “liquid film” on solid–liquid interface in nanofluids has been extensively studied, most research this area examined metal–water or Ar-based nanofluids. work, non-equilibrium molecular dynamics utilized explore mechanism TiO 2 –water It noted that a distinct interfacial layer formed within 5 Å from nanoparticle...
In order to study the movement and shape change characteristic of bubble when passing through interface two kinds liquids with different viscosity, free rising process a single in static stratified was numerically simulated volume-of-fluid method. The results show that, initial height is same, velocity, deformation increase radius. When maximum intensity vortex distributed at top bubble, left right sides bottom sides, spherical, ellipsoid spherical cap respectively. At heights, trajectory...
The lance is a critical component of the bottom-blowing pool melting process, and its placement has an important impact on pool?s gas-liquid two-phase flow. In this study, mathematical model process established, flow pattern, trajectory, wake vortex, velocity bubbles under four spacings are simulated. Results show that there three basic bubble patterns appear in field: coalesce before leaving nozzle (Pattern ?), after no coalescence during rise III). pattern varies from Pattern I to III with...
Abstract During the gas-assisted extrusion process of plastic tubes embedded with antibacterial particles, particles tend to agglomerate. The dispersion effect these agglomerates using nozzle-pressure-difference method is significantly influenced by gas flow state. Therefore, this study establishes nozzle model. state near simulated and analyzed Ansys Fluent software. Gas-assisted experiments are conducted different inlet pressures, size distribution observed electron microscopy. simulation...
In the top submerged lance (TSL) smelting process, flow boiling may occur in lance’s inner pipe due to heat coming from furnace when liquid fuel is adopted. current study, a numerical simulation was carried out by coupling Eulerian two-fluid model with improved RPI wall investigate subcooled n-heptane pipe. The effects of inlet velocity and emissivity on two-phase transfer are elucidated. results show that, for pipes ranging 0.3 m·s−1 1.0 m·s−1, an increase leads lower void fraction near...
