环形生态水槽流动的特性研究

Flow features in circular ecology channel

实测了环形生态水槽内的流速分布。采用柱坐标系下的k -ε湍流模型及SIMPLE算法 ,对该流场进行了数值模拟。从计算结果和实验资料的分析比较看出 ,计算结果可靠。在此流场内进行了钉螺的运动特点的实验研究 ,结果表明钉螺具有流速敏感性 ,对研究钉螺的随流扩散具有重要意义。

The flow velocity distribution in circular ecology channel is investigated The flow field is simulated by employing the k ε turbulence model in cylindrical coordinates The comparison of the computational results and the experimental data shows that the computation is reliable The results can be employed to analyze the movement of the snails in the flow The experiment on the sensitivity of Oncomelania to flow velocity is important to research into the diffusion of Oncomelania with water flow
