| 1 | Cavitation shedding dynamics around a hydrofoil simulated using a filter-based density corrected model显示文摘The unsteady turbulent cloud cavitation around a NACA66 hydrofoil was simulated using the filter-based density corrected model(FBDCM). The cloud cavitation was treated as a homogeneous liquid-vapor mixture and the effects of turbulent eddy viscosity were reduced in cavitation regions near the hydrofoil and in the wake. The numerical results(in terms of the vapor shedding structure and transient pressure pulsation due to cavitation evolution) agree well with the available experimental data, showing the validity of the FBDCM method. Furthermore, the interaction of vortex and cavitation was analyzed based on the vorticity transport equation, revealing that the cavitation evolution has a strong connection with vortex dynamics. A detailed analysis shows that the cavitation could promote the vortex production and flow unsteadiness by the dilatation and baroclinic torque terms in the vorticity transport equation. | YU An JI Bin HUANG RenFang ZHANG Yao ZHANG YuNing LUO XianWu | 2015 | Science China(Technological Sciences)2015，58，5： | 8 |
| 2 | Study on Maintenance and Management Measures of Municipal Drainage System显示文摘With the continuous development of China's modern economy,it has greatly promoted the pace of the process of urbanization.In the construction of urban infrastructure,municipal drainage system occupies the main position,it can clear the city water,beautify the city,and create a comfortable living environment.In order to play the role of the municipal drainage system to the extreme,the relevant departments should put the drainage system's maintenance and management into practice,and find out the problem and solve it in time.Based on the operation of municipal drainage system,this paper discusses the problems encountered in the maintenance and management of drainage system,and puts forward effective solutions to the problems. | Peitao Huang Ming Zhang Xiao Zhang Yuning An Weiming Lu | 2018 | Smart Construction Research2018，2，1： | 0 |
