Valves are the key components used for flow control in process industry, and solid–liquid two-phase is commonly encountered during valve regulation. Solid particles impact wall surfaces cause continuous erosion, which undermines stability reliability of long-term operation. In this study, discrete element method (DEM) was to investigate flow-induced erosion characteristics inside a ball valve. Simulations were conducted different dynamic processes (valve opening closing) particle diameters...
A new structure is proposed for a DN25-type ultrasonic gas flow meter with V-shape double sound channel arrangement. The field characteristics are analyzed including velocity curves the four lines, profiles different cross-sections of meter, and streamlines transducer sections. metering flowmeter measured using Venturi nozzle device. When pipeline rate less than 2.26 m/s, pipe installation does not have significant effect on profile in lines. However, error low-flow region large, distortion...
The integrated electricity–gas energy system (IEGES) coordinates the power and natural gas through P2G equipment, turbines other coupling components. IEGES can realize wide-range long-distance transmission of electricity, heat gas, truly large-scale cross-regional supply in space. At present, theoretical applicable to comprehensive benefit evaluation has not been established, economic, environmental social benefits are still at a preliminary study stage. Therefore, model is constructed,...
In this paper, an energy consumption improvement method for centrifugal pump is proposed by referring to the bionic structure reduce loss of pump. Four types impellers with different sinusoidal tubercle trailing edges (STTE) are designed. Experiment and numerical simulation combined explore beneficial effects STTEs. The entropy generation rate analysis was introduced, calculation results were analyzed internal influence STTE on characteristics Results show that use STTEs can adjust...
A novel multi-objective security-constrained unit commitment model is proposed in this paper considering wind power and electric vehicles. fuzzy chance-constrained program utilized to solve the forecasting errors. We use game theory formulate an EVs energy scheduling game. The distributed management strategy requires each EV owner simply apply its best response current total load tariffs. Numerical simulation was conducted on IEEE 24-bus system demonstrate that synergy between V2G can...
The implementation of renewable energy power consumption policy will have a certain impact on the existing cross-provincial trading market structure generation rights. In addition, possibility producers benefiting from green certificate also an important decision-making both parties. Therefore, this paper studies rights under considering market. Firstly, analyses and then synergistic influence Then, original clearing method is optimized by introducing index factor, game model between two...
For the airlines, safety is foundation for their existence and development. Therefore, management of risks one most important parts daily airline management. Uncertain factors such as weather changes, aircraft failures, employee status all contribute to occurrence various types aviation accidents. How find, manage, avoid through improvement methods, analysis operational data application technical tools problems faced by airlines. Taking Xiamen Airlines an example, this article thoroughly...
With the popularization and application of technologies in energy power industry, Energy Internet has shown more open inclusive characteristics. In this paper, combined with characteristics integrated system evaluation, from three dimensions production, transmission distribution, consumption, established corresponding evaluation index system. At same time, determining weight based on AHP-entropy method, using statistical evidence theory fusion cycle multiple results, avoids influence...
In order to reduce the operation and maintenance costs of a single micro grid adverse effects caused by unnecessary energy interaction between main while improving overall economic benefits community, this paper proposes two-level management model with optimization goal maximizing social welfare community minimizing total electricity cost grid. The lower-level optimizes output each equipment unit in system exchange power external operating microgrid. upper- level Taking microgrid four...
