Average mass transfer coefficients to a rotating and to a vibrating sphere were measured with an electrochemical method.
The rotational velocity of the sphere was varied, as were the frequency and the amplitude of the vibrating sphere. Different Schmidt-numbers were obtained by altering the temperature of the liquid in which the sphere was immersed.
The results can be summarized as follows: Rotating sphere the observations were made at and at Vibrating sphere the observations being made at at and at
