【 摘 要 】

Flows and deformations of free surface of isothermal liquid bridge under the influence of axial vibrations of finite amplitude and frequency in microgravity conditions are studied numerically by Volume of Fluid method. Investigation is carried out in the framework of full non-average approach. Numerical data on instantaneous and average velocity fields and instantaneous and average shapes of free surface of fluid at different vibration frequencies and amplitudes are obtained.
