【摘要】：钉螺是日本血吸虫的唯一中间宿主,研究其在水中的沉降特性与运动特征对防治血吸虫病具有重要意义。该文运用文献中的实测资料对钉螺自由态以及失控态的沉降速度及阻力系数进行了研究;提出了旋流排螺的设想,构建了三维数学模型模拟旋流装置中的水流及钉螺的运动,并对该模型进行了验证计算,结果表明,模型验证的计算成果与已有实测资料吻合良好。
[Abstract]:Oncomelania hupensis is the only intermediate host of Schistosoma japonicum. It is of great significance to study the characteristics of subsidence and motion of snail in water for schistosomiasis control. In this paper, the subsidence velocity and drag coefficient of snail free and out of control are studied by using the measured data in the literature. The idea of spiral conch arrangement is put forward, and a three-dimensional mathematical model is constructed to simulate the movement of water flow and snail in the swirl device. The model is verified and calculated. The results show that the calculated results of the model are in good agreement with the existing measured data.
