EFFECTS OF SOFT MUDS ON FREE OSCILLATION PERIODS IN RECTANGULAR HARBORS
Abstract:
In this paper, effects of fluid muds on one-dimensional free oscillations in rectangular harbors are discussed, with emphasis on the free oscillation periods and decay coefficients. The mathematical model is a layer of inviscid fluid overlaying a viscous fluid with great density, bounded by a horizontal rigid plane and vertical walls. Solutions for initial simple harmonic disturbances indicate that the surface and interface elevations and fluid particle velocities decay exponentially with time. The free oscillation periods increase with the increase of lower layer’s viscosity and decrease with the increase of lower layer’s depth.
