位于青秀山风景区的蜡烛湖是南宁市建设"中国水城"的重要组成部分。为了论证蜡烛湖形态及相关设计的科学性,根据不同入水口流速、出水口数量、位置和湖泊形态设置了5组实验,运用二维流场数值模拟方法,进行模拟研究。结果表明,提高蜡烛湖入水口的流速对于改善蜡烛湖整体流场影响不大,无法解决蜡烛湖大面积水体的"死水"问题;不同出水口的位置和数量对蜡烛湖流场和流速影响较大,其中出水口2、出水口4和出水口5对蜡烛湖流场流速影响最大,能够较好解决蜡烛湖整体流场流速;蜡烛湖的岸线形状对于整个湖泊的流场有较大影响,优化的呈祥岛岸线形态能够改善附近区域静水流场,加快蜡烛湖水流流动;在优化了呈...

Candle Lake at Qingxiu mountain scenic spot is one of the most important parts of the'China Water Town'program in Nanning City. In order to figure out the scientific rationality of the situation and design of water system, four experiment programs were set up based on different inlet flow velocity, quantity and positions of outlets and the shape of center islands to simulate the flow distribution and velocity of Candle Lake by using the method of 2-dimensional numeral simulation. The results indicated that the flow distribution and velocity of Candle Lake could not be improved by increasing th...
