在静止流体中测量了氧向旋转锥体的传质。在施密特数为400的层流和湍流中使用顶角为19.2°、30°、60°、90°、120°和180°的圆锥（圆盘）。层流传质数据与高施密特数下的锥体方程一致。对于顶角大于19.2°的锥体，湍流传质数据与Deissler的高施密特数表达式一致。然而，19.2°的锥角导致传质的实验值大于预测值。最后，从层流到湍流的过渡雷诺数的值，直接从传质数据确定，与以前的结果一致。
The mass transfer of oxygen to a rotating cone has been measured in a quiescent fluid. Cones with vertex angles of 19.2°, 30°, 60°, 90°, 120° and 180° (disks) were used in both laminar and turbulent flow at a Schmidt number of 400. The laminar flow mass transfer data is in agreement with an equation derived for cones at high Schmidt numbers. The turbulent flow mass transfer data for cones with vertex angles greater than 19.2° is in agreement with the high Schmidt number expression of Deissler. The 19.2° cone angle, however, results in experimental values for the mass transfer which are greater than the predicted values. Lastly, the values of the Reynolds number for transition from laminar to turbulent flow, as determined directly from the mass transfer data, are in agreement with previous results.
