Published: January 2021

Abstract
The use of renewable energy has alleviated the severe resource and environmental pressure at this stage. However, the discontinuity and randomness of renewable energy have brought risks to the system, resulting in serious problems of abandoning wind, light, and water, making it impossible to achieve large-scale access to renewable energy. This paper proposes a framework of renewable energy consumption system supported by deep learning, which can provide new solutions for renewable energy consumption under the background of integrated energy service system.

Published: January 2021

Abstract
Biodiesel soot particles (BSPs) and first heat-treated and then acid-treated BSPs (T-BSPs) were employed as lubricant additives for GCr15 steel/316 austenitic stainless steel contacts in aqueous media. Their tribological performances and mechanisms were tested. The result shows that T-BSPs exhibited better lubricating performances than BSPs in aqueous media. Moreover, it is proved that both BSPs and T-BSPs could enter the friction surfaces and prevent the direct steel–steel contact. In addition, T-BSPs exhibited better dispersion in water, which aided uniform adsorption on the friction surfaces, resulting in better friction-reducing and antiwear performances.

Published: January 2021

Abstract
In this paper, the wing tip jet is proposed to improve the aerodynamic performance of the three-dimensional ONERA M6 wing at high Reynolds numbers. The CFD method is used to perform numerical simulation with the SST k-ω two-equation model. To verify present numerical model, ONERA M6 wing at the attack angle(α) of 2° is selected and the simulation results are in good agreement with the experimental data. The flow around the airfoil at high Reynolds number is simulated at 0°-14° attack angle, and the critical attack angle is 11° without jet. Finally, the influence of the jet on the aerodynamic characteristics of the airfoil at different attack angle are studied and it is found that the lift coefficient and lift-drag ratio of the airfoil increase with jet.

Probabilistic Dynamic Optimal Energy Flow Calculation for the gas-electric coupling system
Authors: Xu Shenzhi 
Published: January 2021

Abstract
Due to pollution and energy shortage, the multi-energy interconnected system formed by natural gas and electricity coupling has attracted a lot of attention because of its cleanness and high efficiency. The operation of natural gas system and electrical power system belong to different time scales. At the same time, more and more new energy sources such as wind and photovoltaic power generation in the electrical power system increase the uncertainty of power supply. The operation of gas-electric coupling system must consider the impact of these factors. In response to these problems, this paper considers the impact of timing on the operating state of gas-electric coupling system based on the multi-period optimization model, and proposes a probabilistic energy flow calculation method, namely the Latin Hypercube sampling Markov Chain simulation (LHMCS). This method can quickly obtain the influence of random factors on the operating state of gas-electric coupling system. Finally, a simulation example verifies the rationality and effectiveness of the method proposed.

Published: January 2021

Abstract
Biogas slurry can be used as a nitrogen (N) fertilizer, and has been suggested to reduce chemical fertilizer input and improve vegetable quality. The present study aimed to evaluate the effects of vegetable waste biogas slurry topdressing on the yield, quality and nitrogen (N) use efficiency of cauliflower. A field experiment consisting of five treatments during topdressing (CK: no N input, CON: farmer’s conventional N fertilizer input, HBS: substitution of half the amount of N fertilizer with vegetable waste biogas slurry, BS: substitution of the total amount of N fertilizer with vegetable waste biogas slurry, and DBS: substitution of double the amount of N fertilizer with vegetable waste biogas slurry) was conducted. When compared with that of the CON treatment, the HBS, BS, and DBS treatments increased the yield of cauliflower by 4.7%, 13.7%, and 15.3%, respectively. Furthermore, the BS and DBS treatments improved cauliflower quality compared with that of the CON treatment. The HBS and BS treatments increased the N use efficiency and the DBS treatment reduced the N use efficiency compared with that of the CON treatment. Considering the increased fruit quality and N use efficiency, the substitution of fertilizer N with equal amount of vegetable waste biogas slurry during topdressing in the production of cauliflower is recommended in northern China.

Authors: Pengcheng Qiu , Pengxiang Qiu 
Published: January 2021

Abstract
Silicon-based solar cells are an important field for the development of the photovoltaic industry. The grid electrode on the front surface of the traditional silicon solar cell causes shading loss. However, the positive and negative electrodes are placed on the back surface of the interdigitated back contact(IBC) solar cell, which causes no shading loss and improvement of photoelectric conversion efficiency. The core of the IBC silicon solar cell is the interface control, field effect control and the design of the positive and negative electrode patterns on the back. Different manufacturing processes ensure the accuracy of the grid electrode and reduce production costs. This paper systematically introduces the structure and interface characteristics and development history of IBC solar cells, and looks forward to the development trend and application prospects of IBC solar cells.

Authors: Jing Yangyang , Li Tielong , Zhu Xiaojing , Zhang Nan , Xia Ziwei 
Published: January 2021

Abstract
The HYDRUS-1D model is used to analyze the sensitivity of various soil hydraulic parameters under constant head infiltration conditions. The results show that: under constant head infiltration conditions, the perturbation of each parameter is sensitive to the impact of soil water potential, the order is: n>θs>Ks>a>θr, where n is a parameter which has a greater impact on the simulation results of soil water potential. The sensitivity order of the influence of each parameter on the cumulative infiltration is: Ks>n>θs>θr>a, where Ks and n are the parameters that have greater impacts on the cumulative infiltration. Under the constant water head infiltration condition of sewage irrigation, simulation analysis should calibrate the accuracy of n, Ks and θs parameters.
Sensitivity analysis of wave direction in wave numerical model
Authors: zhen Liu , Han-bao Chen , Ya-nan Xu , Yong-zhou Cheng , Zhao-xu  
Published: January 2021

Abstract
The sensitivity analysis of wave direction is carried out for three cases, namely, the excavation of outer channel, surge and typhoon in the shield port. The results show that for the sheltered port with excavated outer channel, the wave direction sensitivity near the entrance is strong, and the one-way wave sensitivity is stronger than the multi-directional wave, so it is suggested that the main wave direction analysis should be densified to 32 azimuth angle; for the swell sea area, when its long-period characteristics lead to the wave near shore transmission process, the greater the wave direction change, the more concentrated the wave direction perpendicular to the shoreline, so the wave direction of the swell sea area is divided. For the influence of typhoon, the wave direction should consider the possibility of the change of the strong typhoon path, and for the strong wave direction, it is suggested to be Increased to the four or eight azimuth.

Authors: Peng Cheng , Chen Song Gui , Wang Yi Na 
Published: January 2021

Abstract
This article contraposes the sand blocking characteristics of silt curtain in the ocean nearshore settling basin, two-dimension physical model experiments were conducted to study the horizontal permeability coefficient and sand blocking effectiveness. The effects of different elements (current speed, tide level and sediment grain size) were considered respectively to analyze the influence of sand blocking effectiveness. The results show that, the horizontal permeability coefficient of silt curtain is not only related to the size, shape and connectivity of pore structure, but also depends on the sandiness water movement where it is in. The horizontal permeability coefficient reduces with the current speed increase. The silt curtain shows a higher sand blocking characteristic for a larger sediment grain size. The faster current speed and the bigger sand-carrying gap that is it means the higher tide level leads to more obvious sand blocking effectiveness decrease with other conditions unchanged.

Abstract
The bay of Bengal is an important sea area of the 21st century Maritime Silk Road. Systematic analysis of the hydrodynamic and sediment characteristics of the bay of Bengal is conducive to the development and implementation of offshore and coastal projects in the bay of Bengal. In this paper, based on the historical reanalysis data of ECMWF and the observed data of several hydrological stations along the east coast of Bangladesh, including wave, tide level, tidal current and sediment data are verified and assimilated, and the characteristics of wind wave, water level, tide and sediment along the east coast of Bengal are analysed. The hydrodynamic and sediment conditions in the bay of Bengal are generally characterized by “strong tide, strong wave and high suspended sediment concentration”. The bay of Bengal is easily affected by cyclonic storms, which causes a great increase in storm surge. The above situation will lead to the complicated sediment erosion and deposition of storm surge, strong wave and strong tide and high suspended sediment concentration. At present, there has no deep-water port and coastal power plant located in the bay of Bengal. Whether to build a deep-water port or how to transfer at sea should be paid attention to or studied in depth.

Published: January 2021

Abstract
The research uses the wave parameters of OWI and ECMWF including wave height, period and direction, and analysis the wave characteristics of the sea area throughout the year and the wave characteristics of the NW wave. For the analysis of wave characteristics of waves biased to NW, OWI analysis biased towards NW waves in which wind and waves accounted for 62.6% and swells accounted for 37.4%, showing mixed wave characteristics dominated by wind and waves; while ECMWF analysis was biased towards NW waves. Wind and waves accounted for 24.5%, and swells accounted for 75.4%. There are big differences between the two data sources in the wave pattern analysis of NW direction. The research further uses the model to calculate and analyze the wave conditions of the Bay of Bengal waters affected by the monsoon (without considering the introduction of ocean waves). The results also show that the NW wave is characterized by a mixed wave feature dominated by wind and waves. The proportion of wind and waves is 76.1%, the proportion of swell is 23.6%, the average period is about 4.7s, and the maximum average period is less than 9s. From the analysis of the calculated directional spectrum, the biased NW wave caused by the monsoon also shows the characteristics of a bimodal spectrum, in which the wave energy is mainly reflected in the average period of about 5s. The research results show that the NW wave is a mixed wave feature dominated by wind and waves. There are long peak wave swells in the wave train, and the wave height and periodic characteristic values are relatively small.
