| 1 | 复合材料立管涡激振动数值计算显示文摘基于尺度自适应模拟(SAS)和计算结构力学(CSD),对复合材料海洋热塑性增强立管(Reinforced Thermoplastic Pipe,RTP)涡激振动响应进行数值计算.数值计算了聚氯乙烯(PVC)立管涡激振动响应和复合材料层合板模态,并与实验数据对比,验证了文中双向流固耦合方法和复合材料建模的准确性.并且,分别计算了不同条件下的RTP立管和相同尺寸的钢制立管的涡激振动响应.计算结果表明:来流速度为0.1m/s时,RTP立管都发生了频率锁定现象;RTP立管的来流向振动响应和横向振动响应同样重要,不可忽略;来流向振动响应及流场三维效应导致立管中部区域振动响应的轨迹比较杂乱;来流速度为0.2m/s时,相同尺寸的钢制立管的来流向和横向振幅比RTP立管的小,且钢制立管主要是低阶模态振动;铰-铰约束情况下的RTP立管的振幅相比固定-固定约束情况下的整体上稍大,且主要是2、3阶振型运动. | 陈东阳 ABBAS L K 王国平 芮筱亭 陆卫杰 | 2017 | 上海交通大学学报2017，51，4： | 3 |
| 2 | Predicting groundwater level of wells in the Diyala River Basin in eastern Iraq using artificial neural network显示文摘Al-Mansourieh zone is a part of Al-Khalis City within the province of Diyala and located in the Diyala River Basin in eastern Iraq with a total area about 830 km2.Groundwater is the main water source for agriculture in this zone.Random well drilling without geological and hydraulic information has led the most of these wells to dry up quickly.Therefore,it is necessary to estimate the levels of groundwater in wells through observed data.In this study,Alyuda NeroIntelligance 2.1 software was applied to predict the groundwater levels in 244 wells using sets of measured data.These data included the coordinates of wells(x,y),elevations,well depth,discharge and groundwater levels.Three ANN structures(5-3-3-1,5-10-10-1 and 5-11-11-1)were used to predict the groundwater levels and to acquire the best matching between the measured and ANN predicted values.The coefficient of correlation,coefficient determination(R2)and sum-square error(SSE)were used to evaluate the performance of the ANN models.According to the ANN results,the model with the three structures has a good predictability and proves more effective for determining groundwater level in wells.The best predictor was achieved in the structure 5-3-3-1,with R2 about 0.92,0.89,0.84 and 0.91 in training,validation,testing and all processes respectively.The minimum average error in the best predictor is achieved in validation and testing processes at about 0.130 and 0.171 respectively.On the other hand,the results indicated that the model has the potential to determine the appropriate places for drilling the wells to obtain the highest level of groundwater. | Abdulrahman Th Mohammad Qassem H Jalut Nadia L Abbas | 2020 | Journal of Groundwater Science and Engineering2020，8，1： | 2 |
