Ports around Belitung Island have an essential role in supporting inter-island shipping activities, which positively impact economic growth. So that predictions to find out the condition of waters need be made early anticipate disruption ship's lanes. This study's prediction these was carried with a hydrodynamic model. Model accuracy (calibration) compares model results survey data. Based on se...

Abstract To improve the rotation efficiency of amphibious aircraft on water surface, CFD technology is used to simulate maneuverable motion in this paper. The numerical calculations direct navigation, oblique towing, no drift angle rotating arm motion, navigation with rudder, and planar are carried out, respectively. hydrodynamic derivatives such as position derivative, coupling rudder added ma...
