摘要
这项工作研究了隔墙或挡板对水库水力参数和水滞留时间的影响。为此,水系统配备了遥感(RS)、联网传感器、先进的调制解调器和数据记录器。研究显示了如何通过物联网和 RS 控制水力参数。较长的滞留时间导致混凝土中的钢筋在氯的存在下氧化,增加了水流失的可能性。这项工作还展示了如何降低水库漏水的概率。计算流体动力学分析结果表明,在两个挡板的情况下,所形成的三个区域出现了三个涡流。较好的流体相互渗透缩短了滞留时间。在形成涡流的区域,涡流数量减少,停留时间增加。回归分析表明,水库入口流和出口流的 P 值分别为 0.998 和 0.977(两个挡板垂直于流向)。曲线估算结果表明,幂函数与散点图具有适当的相关性,曲线拟合效果最佳。
Computational fluid dynamics analysis for smart control of water supply
This work investigated the partition walls or baffles’ effects on hydraulic parameters and water retention time in a reservoir. According to this aim, the water system was equipped with remote sensing (RS), networked sensors, advanced modems, and data loggers. The study showed how to control hydraulic parameters by the Internet of things and RS. The higher retention time led to the probability growth of rebar oxidation in concrete in the presence of chlorine and increased the possibility of water loss. This work also showed how to decrease the probability of water leakage in reservoirs. The computational fluid dynamics analysis results showed that the two baffles case led to the emergence of three eddy currents in the three zones created. The better fluid interpenetration caused the reduction in retention time. In the areas where the vortex was formed, the number of eddy currents decreased and the retention time increased. Regression analysis showed that the P value was 0.998 and 0.977 for the inlet flow and outlet flow for the reservoir, respectively (two baffles case perpendicular to the flow direction). The curve estimation showed that the power function had a suitable correlation on the scatter diagram and with the best curve fit.
