Abstract

This article is about applying of CFD for calculation and simulation the tidal stream on the navigable fairway in general. Its feasibility study result will be used for the pilot implementation on the Hai Phong fairway in Vietnam. By using the input from the geometry data of the fairway and the data from the annual tide table of Vietnam, therefore, the calculation is taking place to show the velocity field of tidal stream (including direction and speed) according to the time on fairway. In order to answer the research question, the authors combine field study, survey data and measurement data to assess factors that influence the input. The objective is to ensure the appropriateness of the simulation within the Haiphong fairway. For instance, taking into account the weather conditions, excluding the abnormal factors that might affect the characteristics of the current (floods, storms,…). This study will lay a foundation for deploying the mapping service of the tidal stream for safe navigation on the navigation fairway.
