Abstract

The problem of incompressible two-dimensional viscous flow past an infinite prism of rectangular cross section subjected to forced or free oscillation in the transverse direction is considered. The complete Reynolds equations, closed by means of a two-parameterκ-τ-model of turbulence, are solved numerically in the noninertial coordinate system. The coefficients of the aerodynamic forces acting on the body are calculated as time functions; in the case of free oscillations the paths of the body and the instantaneous velocities of the oscillatory motion are calculated.
