Contact line dynamics in ship hydrodynamics

Abstract

Interfaces are ubiquitous in nature and technology. In a fluid flow problem, interfaces oftenform the boundary of the domain where the extent of mass, momentum and energy transferacross it must be known. Specifying the correct boundary conditions is essential in makingaccurate predictions. One of the boundary conditions that has intrigued researchers for over acentury is the velocity boundary condition at the contact line, associated with a two phase flowsuch as the interface of ocean surface and the hull of a ship. Understanding the contact linedynamics has been of interest to researchers due to its widespread applications in properhydrodynamic prediction around a surface vehicle. The application that is of special interesthere is that of ship hydrodynamics. The inherent two~phase nature of the environment in whicha ship operates makes understanding the contact line dynamics very important. In this proposalours goals are to understand and develop a boundary condition that capture the dynamics ofthe contact line in both steady and unsteady flow and; to implement the developed boundarycondition in a continuum scale problem which poses a unique challenge due to the multiscalenature of the problem.
