Compared with the hydrogen jet fire from a pressure vessel in an open space, the hydrogen jet fire inside a tunnel has a different kind of risk because of the semi-enclosed space. In this study, computational fluid dynamics (CFD) simulations of the hydrogen jet fire from a hydrogen transport vehicle inside a tunnel were carried out. Several different factors, such as hydrogen leakage rate, leakage area, longitudinal ventilation, transverse ventilation and the volume of the tunnel, were considered to analyze the influence on the temperature and diffusion of hydrogen inside the tunnel during the jet fire. The results show that compared with an open space, the hazards of the hydrogen jet fire inside a tunnel lie in not only high temperature but also the accumulation of hydrogen, which may pose a secondary disaster inside the tunnel. In order to control the hazard and avoid a secondary disaster after the hydrogen jet fire happened, enough longitudinal and transverse ventilation is necessary inside the tunnel. Keywords—computational fluid dynamics simulations; hydrogen jet fire; tunnel fire; dangerous chemical transport

With the development of China's economy and its sheer size, the increasingly pursuit of a better life, people's demands for the environment and health are getting bigger and bigger. Due to traditional lifestyles and habits, rural people still use unclean and Non-environmental power sources. Most of them use coal and firewood to heat and cook, which seriously affects the development and progress of rural economic and social development. The construction of rural energy systems is becoming increasingly urgent. In order to study this system in Tianjin, we selected five representative villages in Tianjin. Through interviews and questionnaire surveys, we summarized the current situation of rural energy use in Tianjin and found out many problems such as imperfect systems. We have developed corresponding countermeasures for the construction of it. In order to improve the environmental quality of rural areas, study and explore the construction of rural energy system, and help Tianjin rural revitalization, we conducted research on five suburban rural areas in Tianjin, conducted research and study through different typical villages, and fully understood the specific use of rural energy in Tianjin. The paper will explore countermeasures for the construction of rural energy system in Tianjin. Keywords—rural energy system; construction; environmental protection; rural revitalization I.

To understand the microbial community characteristics and denitrification status in coastal water ecosystem of Bohai Bay, China, the bacterioplankton from six representative stations were collected in September 2016, and the bacterial community and abundance of nir-encoding denitrifying bacteria were studied by 454-pyrosequencing and real-time quantitative PCR (qPCR), respectively. The results showed that the Shannon index of the bacterial community ranged from 4.86 to 5.56. The bacterial composition and their relative abundance varied significantly among the bacterial libraries from the six water samples. Proteobacteria was the largest phylum in the six samples varying between 63.19% and 77.34%. α-proteobacteria was the most abundant class in the W4 station with 46.09%, while γ-proteobacteria was the most abundant class in other five stations ranging from 36.39% to 60.58%. The qPCR results showed that the nirS gene abundance ranged from 2.26×107 copies/L to 9.63×107 copies/L, while nirK gene ranged from 1.01×106 copies/L to 2.09×107 copies/L, indicating that both of them played important roles during the denitrification of the local coastal water. Furthermore, the nirS abundance in each station was significantly higher than that of nirK, suggesting that the functional genes nirS played more important role than nirK in reduction process of nitrite (NO2-) to nitric oxide (NO). Canonical correspondence analysis (CCA) results indicated that petroleum, arsenic (As), chromium (Cr), lead (Pb) and cadmium (Cd) had significant effects on the distribution of bacterial community. In contrast, the key factors regulating the nirS and nirK gene abundances included nitrate (NO3-N), phosphate (PO3-P), chlorophyll a (Chla), As and Cd. Keywords—Bohai Sea; bacteria; denitrification; pyrosequencing; real-time quantitative PCR (qPCR)

In order to solve the problem of peak shaving capacity in power system caused by high permeability of renewable energy, this paper proposed a cascaded hydropower "Virtual pumped storage power station" scheduling method. The "Virtual pumped storage power station" model of cascade hydropower stations is established by studying the coupling relationship between each cascaded hydropower stations, simulating the operation of pumped storage power stations from both hydraulic and electrical aspects. Under the constraints of cascaded hydropower stations, the objective function of peak shaving power of "virtual pumped power station" is constructed and figured out. The simulation results prove that the cascaded hydropower scheduling from this method is able to significantly improve flexibility and economy of cascaded hydropower, and taps the peak shaving potential of cascaded hydropower sufficiently.

At present, most energy-saving studies on tunnel lighting are theoretical or emulational, fewer are experimental studies. Based on optimized tunnel lamp installation parameters, a simulation experiment of tunnel lighting and a tunnel model experiment of lighting were carried out to study the energy-saving of tunnel lighting with low cost. Yanlieshan highway tunnel was selected as object, the optimized central lamp installation parameters (OCLIPs) were obtained with the lighting parameters optimization model (LPOM) on central lamp distribution (CLD) from reference on the basis of tunnel structure sizes (TSS) and selected LED lamps. Simulation experiment of the tunnel lighting was accomplished with DIALux based on the TSS and OCLIPs. A similar tunnel model was designed and built according to the TSS and similarity theory, a lighting experiment was accomplished with the similar tunnel model, and the road-surface-illuminance (RSI) data were obtained and reversely treated, and compared with the simulation experiment results, the statistical results of horizontal RSI of the two ways coincides well, which proves the correctness of the LPOM, the feasibility of the lighting experimental study with tunnel model and validity of the experiment method.

Evaluation of ecological benefit of sea area utilization is an important technology for decision support in marine spatial planning process. In this paper, a model of ecological benefit evaluation of marine based on lattice marine units is developed, in which the spatial data processing flow and non-spatial data processing flow are separated. The model calculation is decoupled with GIS platform, which is developed by object oriented programming. Two applications are developed based on the model, one is a comprehensive benefit analysis of maximum sea area utilization, and the other is an ecological benefit loss analysis of current utilization of marine. The model application results show that the model automated computing process based on different scenario parameters can support the decision making process of marine planning and management without GIS platform support.

A high-impact heavy rainfall event occurred in Beijing, China on 16 July 2018, which is a typical warm sector heavy rainfall associated with Mesoscale Convective System (MCS) of multi cells. To clarify the key factors influencing the heavy rainfall, ensemble sensitivity analysis (ESA) is conducted using the state-of-the-art European Centre for Medium-Range Weather Forecasts (ECMWF) ensemble prediction system. The ESA is a new efficient tool utilizing the information contained in ensemble forecast to calculate a linear relationship between a forecast metric and model perturbation variable. Results show that the low-level southwestly moist flow plays a significant role in the heavy rainfall in Beijing which is favorable for abundant water vapor and dynamic lifting. Keywords—ensemble sensitivity analysis; heavy rainfall; ensemble prediction system
