CALCULATION OF OSCILLATIONS OF A CYLINDRICAL PENDULUM IN A CAVITY FILLED WITH A VISCOUS FLUID WITH THE USE OF SLIDING MULTIBLOCK GRIDS
P. A. Baranov, S. A. Isaev, N. A. Kudryavtsev, and V. B. Kharchenko UDC 532.517.2 The characteristics of the oscillations of a cylindrical pendulum in a square cavity filled with an incompressible viscous fluid have been forecast on the basis of the joint numerical modeling of two-dimensional unsteady laminar flow around a circular cylinder with the use of movable sliding grids and solution of dynamic equations.
