【 摘 要 】

We consider fluid flow in an axial gap around the smooth disc rotating in a closed cavity. According to the results of experiments on different working fluids in a wide range of operating modes for smooth discs, the formula is presented to determine the coefficient of fluid flow spin subject to a rate fluid flow from the periphery to the center. On the basis of the experimental data the empirical formula is obtained for the friction torque with respect to a rate fluid flow.
