【摘要】：釘螺是日本血吸蟲的唯一中間宿主,研究其在水中的沉降特性與運(yùn)動(dòng)特征對(duì)防治血吸蟲病具有重要意義。該文運(yùn)用文獻(xiàn)中的實(shí)測(cè)資料對(duì)釘螺自由態(tài)以及失控態(tài)的沉降速度及阻力系數(shù)進(jìn)行了研究;提出了旋流排螺的設(shè)想,構(gòu)建了三維數(shù)學(xué)模型模擬旋流裝置中的水流及釘螺的運(yùn)動(dòng),并對(duì)該模型進(jìn)行了驗(yàn)證計(jì)算,結(jié)果表明,模型驗(yàn)證的計(jì)算成果與已有實(shí)測(cè)資料吻合良好。
[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.
