Authors: Wang Hanqing , Zhao Yue , Tian Ling
Published: June 2019

The double-diffusion mixed convection in a rectangular cavity with a porous structure was studied using numerical simulation. The influence of the Rayleigh number Ra, the porosity of the porous structure, the buoyancy ratio N and the distance of the porous structure from the left wall surface Xp on the flow characteristics were discussed by streamline, heatline, massline, Nu and Sh. It is found that the low floating-to-lift ratio has little effect on the heat transfer. When the buoyancy ratio is 5, the Nu number is linearly positively correlated with the porosity. When N<-1, the heat and mass transfer intensity is inversely proportional to the lift-up ratio.

Authors: Zhang G Z , Huang S C , Zhou H M
Published: June 2019

Coastal artificial lakes were encouraged to construct in China for coastal areas remediation. However, it was difficult to keep good water quality. This study investigated water quality improvement strategies for a new coastal artificial lake, located on the coast of Zhejiang Province, China. The expected objectives of water quality in the lake were identified as controlling of algae outbreak accidents under medium eutrophication state, transparency of 1.2 m and ensuring other water quality indicators to maintain or lower than the source water quality. Water exchange was implemented, and the water retention time was designed to be less than 30 days. The sediment could be mostly removed after precipitation in the preliminary precipitation basin. For phosphorus reduction, phosphorus concentration change was predicted by box model. Suppose the active phosphate concentration of inflow water was 0.02 mg/L, when the supplied water volume increased to 18 million m3/a, the active phosphate concentration of the lake could achieve 0.03mg/L. As the water quality was poor in summer, the amount of water supplied was suggested increased. This study established feasible water quality guidelines for sustainable operation, and suggested effective water quality improvement strategies for similar coastal artificial lakes.

Authors: Liu Junzhi , Liu Quan , Feng Yanqing
Published: June 2019

Since the fast development of prefabricated building industry facilitate the light thin – walled steel application in both low residential building and fast construction, better understanding of the labour intensive fabrication of connection indicates the problems of optimized connection design and reduced manufacturing cost can be addressed. Several parameters such as number of screws and configurations of the screw layout were varied to study the impact on shear strength. Since the connection strength governs the structural behavior of the truss system which is the main part of modern thin – walled steel structure, the connection strength is calculated according to the American Iron and Steel Institute (AISI), Euro code, and Chinese specification respectively. The main failure mode occurred in self – drilling screw connections are found to be the tilting and bearing failure based on 84 single lap shear test. All testing specimens have experience four stages. When the spacing is fixed to certain number and the screw is less than six, the effect of configuration patter on the resistance capacity is very limited. In contrast, if the screw number is more than six, certain patter layout could lead to better overall strength compare with normal layout patter and the group effect factor is becoming as a constant. The strength of connection can be increased by enlarging the screw spacing with certain range.

Discussion on the Organization Structure of Large University Campus Planning
Authors: li Yanwei
Published: June 2019

After the expansion of college enrollment, China’s university campus area has become larger and larger. The traditional university campus planning in china is influenced by the planning method of the Soviet period, which emphasizes the function zoning. This increases the distance between the student dormitory and the teaching building, the dining hall and so on. And this has brought trouble to the study and life of college students. So scholars must study the planning and organization of large-scale campus. The most important function of the university campus is to provide students with ideal learning and living place. Designers should adopt the idea of "student oriented" to construct the college campus. The university campus planning should be committed to building a suitable walking space to meet the daily activities of students.For large university campus, in order to create a suitable space for walking, designers should gather the students’ daily life, learning function in a walkable space, forming a composite "functional group". In order to meet the requirements of the appropriate walking distance, each functional group should have a proper service radius. Functional groups can form a composite space. Thus, functional group of university campus planning organizational structure can help to solve this problem. It is more suitable for large-scale campus planning.

The results showed the tourism CE was 111.84×104 t in 2001, and increased to 376.04×104 t in 2015, with the annual growth amount of 18.87×104t and rate of 9.05%, respectively. This denoted Hubei’s tourism was being thoroughly developed on the whole from 2001 to 2015. Then, the share of tourism transport CE was always not less than 62% during 2001-2015, which indicated tourism transport sector should be paid more attention to and be given more of corresponding mitigation countermeasures. Furthermore, tourism activities’ CE was always becoming larger and larger, with the increases of people’s living standard and leisure time. Thus, it was necessary to study on how to improve the efficiency of energy use, especially in the progress of tourism activities. Last, an overall weak decoupling relationship between tourism economy and the corresponding CE existed within Hubei in 2001-2015. Thus, the economic development mode of Hubei’s tourism industry was transforming to the low-carbon pattern expected by us, but it still needed to be continually strengthened.

Authors: Zhang Zhe , Wang Teng
Published: June 2019

The pile foundation is often affected by friction fatigue during pile installation and cyclic loading. In order to study the fatigue behavior of it, the installation and cyclic experiments were carried out using pile foundation model test device. The effects of cycle numbers, cumulative displacement on the pile load performance were studied in the experiments. The results show that the friction fatigue appears with different degrees on pile installation and cyclic process. During installation from soil surface, the soil plug increases and eventually remains constant, and the pile head load increases with the increase of penetration displacement, while the horizontal stress on pile shaft decreased with the increase of h/R because of lower relative displacement. In the cyclic load stage, pile head load and base resistance stresses decrease rapidly in the 5 cycles and gradually restore to 68% and 112% respectively, while the horizontal stress reduces to stable in cyclic load and the fatigue behavior is more significant with lower value of h/R due to the higher degree of soil particle breakage.

The present paper, assisted by the corpus software, carries out a data mining research on the lexical co-occurrence features and explores an empirical study of semantic preferences in Construction Engineering English. The semantic co-occurrence research has been conducted from three aspects involving lexical categories, lexical collocations and lexical colligations. With data retrieval and context analysis, the present research has found out that the lexical categories of Construction Engineering English are limited to seven fields, which are chemical substance, construction materials, structures, positions & measurement, natural environment, living environment and force. Besides, lexicons in different categories demonstrate distinctive semantic preferences and collocation features. And the semantic colligations of Construction Engineering lexicons are majorly neutral in semantic preference, which further proves the neutral and objective characteristics of technology articles.

With the low-end industries continuous migration to low-income countries, China has the high requirement to upgrade the level of productive services. This research discussed the spatial aggregation of global producer services from three major aspects, research history, levels and conclusions. and explored the following characteristics: the research perspective shifts from the spatial characteristics of geography-based summaries to the multi-factors of industrial economy, society, and enterprise management. The research level is based on macro research, and gradually moves toward medium and onlookers to better guide urban construction; research conclusions are distributed from static spatial distribution to the dynamic analysis causes of industrial decision-making. In the future, under the support of informatization and big data, the research on the spatial aggregation of productive service industry will inevitably shift from the analysis of historical spatial characteristics to the analysis of corporate spatial decision-making in the context of analyzing social and economic development trends. The development path can better guide the dynamic development of the space gathering of the industry in the future by considering Chinese characteristics.

Effectiveness analysis of opposing jet thermal protection with hot fuel gas
Authors: Shen Bin Xian , Liu Wei Qiang
Published: June 2019

The hot fuel gas generating with solid fuel was introduced to an opposing jet thermal protection system(TPS), saving the occupied space and reducing the weight of the gas supply system. In this study, the thermal protection performance of opposing jet TPS with hot fuel gas is investigated. The surface heat flux is initially obtained by solving the Reynolds-average Navier-Stokes(RANS) equations coupled with the Menter’s shear stress transport (SST) model. Then, the obtained heat flux is loaded to the blunt body to solve the temperature distribution. The influence of the hot fuel gas on the opposing jet TPS was analyzed with different flying condition. Results show that the hot fuel gas reduces the insulating capacity of the opposing jet, but the peak heat flux exhibits a prominent reduction in contrast to that without injection. The surface temperature also reduces a lot even the hot fuel gas is adopted than that without injection. To obtain a good cooling efficiency, the jet pressure is enhanced. With a higher jet pressure, the surface heat flux, as well as the surface temperature, is reduced, and the similar cooling efficiency can be obtained compared to that with normal coolant.
