The Numerical Analysis of Multiple Layers Current in the Fishery Port using the Finite Elements Methods
Abstract
In the past, the fishery port was used to provide us with product which is related to sea but currently fishery port is realized that the port is not only area of production but also area of recreation. Recently, the concern about development of waterfront in fishery port and harbor have been increase, several harbor remodeling projects have been actively progressed all over the world. But, these development have the duplicity that create a comfortable waterfront and worsen a sea water quality in fishery port and harbor at the same time. For these developments in the waterfront, current analysis in the fishery port have to consider first.

Also, studies in the country is carried out numerical analysis with one-layer model but one-layer model has limit because it is not only ignored the velocity of vertical direction but also assumed equally density and viscosity from surface layer to bottom layer. Therefore, this study is carried out numerical analysis by using multiple layers model that is considered velocity of vertical direction. The results of numerical analysis on current multiple-layers are shown as variously visualized method and these improve numerical analysis about the current. The finite elements is used to do research and Jumunjin fishery port that established the SEB currently is choosen as the object of numerical analysis.

From these results, seawater circulation on the inside area was improved and it that is used with multiple-layers model has result of high accuracy than one-layer model.
