Research Of Numerical Simulation On Turbulent Wave Around Port Structure

As a infrastructure in the society,port enhances our country economy and improves our standard of living greatly.TO fit the requirement of international trade and the trend of transport watercraft biger and biger,the size of port will be increased accordingly,and the deapth of water in sea-route.Most of the good port sites having natural self-covering have been opened out,port construction now faces to deap water and big wave sea area.So people pay more and more attention to the popular structures in port construction such as seawall, big diameter cylinder and so on,their load received from wave and the wave distortion,water velocity around them.This paper mainly study for the load distribution on the faces of several typical port structures,and the influence to the water including velocity and the interface of wave.In this paper, the author first introduces some kinds of interface-tracking method presently,compars the merit and shortcoming each one and adopts the VOF method to capture the wave-air interface.Secondly introduces the methods in the simulation of turbulent flow and turbulent models must use,and compares the models in theory.Then take the under water square seawall for example,three results caculated from laminar flow, k ?εturbulent model, Smagorinsky LES are compared.Thirdly based on OpenFOAM(an Open Source object-oriented C++ library in CFD),wave making boundary and wave absorbing boundary are created.Finally study for the above water square seawall,under water semicircular seawall and large diameter columnar structure,the load they received from wave and the changement of wave shape around them.
