Определение собственной частоты колебаний жидкости с помощью метода интегральных коэффициентов

Abstract

Using the method of integral coefficients obtained by a simple algebraic expression to determine the natural frequency of fluid with free surface in the capacity of complex shape (between coaxial cylinders). Necessary empirical coefficient determined experimentally. Deviation calculated by the formula obtained values of the natural frequency of the experimental values is less than 4% over this range diameter ratio, due consideration to the capacity of the cylinders. This error is acceptable, not only for assessment but also for engineering calculations.
