Abstract

The analytical relationship between the delivery-rate criterion of an axial flow impeller and the power criterion has been found using the angular momentum equation as a basis. This relationship was derived under the assumption of a constant field of tangential velocities along the height of a mixer. Based on the experimentally found velocity fields available in the literature, the equation for calculating the coefficient of proportionality between the delivery rate of a flow impeller and the circulation flow rate is obtained. The published experimental delivery rates and circulation flow rates of a flow impeller are compared with their calculated values found by the proposed equations.

壁挂式搅拌机轴流叶轮的输送速率

摘要

以角动量方程为基础，找到了轴流式叶轮的输出速率准则与功率准则之间的解析关系。该关系是在沿着混合器高度的切线速度恒定场的假设下得出的。基于文献中的实验发现的速度场，获得了用于计算流量叶轮的输送速度和循环流量之间的比例系数的方程式。将已发布的实验性流量和叶轮的循环流量与通过建议的方程式找到的计算值进行比较。
