Initial results are presented from an investigation of the fluid-mechanical characteristics of liquid films on spinning geometries. Available numerical and analytical studies of the fluid-mechanical characteristics of spinning films are also summarized, and the measurements are given for average film thickness as a function of radial position, liquid flow rate, and rotational speed. In spite of surface-tension phenomena not accounted for in the theoretical study, the data indicate that the theory predicts the proper relative effects of the several variables.
