Description:A study is made of the oscillatory flow of a viscous incompressiblefluid with a free surface, in the presence of a fixed vertical circular cylinder. An expression is derived for the oscillatory wave-induced force on the cylinder. The analysis is based on the linearized equations of motion for the fluid, invoking the "small wave amplitude" assumption, but including the viscous terms. The results are compared with the inviscid solution by Havelock, and the solution for an oscillating cylinder in an infinite viscous fluid obtained by Stokes. The results clearly show the combined effects of the inviscid drag force due to the reflected wave and viscous drag force. As the frequency-viscosity parameter R , similar to Reynolds Number, approaches infinity, the solution reduces exactly to the inviscid case.
