Experimental and Numerical Investigations on Flooding System of Iranian South-Coast Dry Docks


Department of Civil Engineering,Tarbiat Modares University


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
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.
