چکیده
Experimental investigations were carried out on the ooding system of the Bandar-Abbas dry dock, located on the southern coast of Iran. The main goal of the investigation was to evaluate the ooding time, as well as the seawater ow speci cations, in the intake channels. The time variable upstream and downstream boundary conditions were simulated. The e ects of tidal uctuations on water discharge through the intake channels were inspected. The ow pattern around the bed over ow weirs of the intake channel was also investigated. The air trapping at the top of the main intake channel was recognized as an e ective phenomenon on the ooding rate. A numerical model is simultaneously developed to evaluate the ow pattern and the velocity and pressure domain in the watering channels. Applicable guidance about selection of the element type and optimization of the convergence rate of the numerical modeling was presented especially for ow simulation under unsteady boundary conditions and complex geometry. Numerical results were compared with corresponding laboratory measured data and a good agreement was obtained.
