A NUMERICAL INVESTIGATION OF MULTIPHASE FLOW AND OIL SPILL IN ISTANBUL STRAIT

Abstract

Istanbul Strait is a globally important inland sea region connecting two continents. It is the most crowded and dangerous strait succeeding Strait of Malacca. Istanbul Strait‟s traffic density is 3 times of Suez Canal, 4 times of Panama Canal because of international sea traffic and this density is increasing every day, so it is becoming more dangerous. To decrease this danger, the flow in the strait must be investigated in a realistic way by using present opportunities. In this study, a part of Istanbul Strait is modeled by a commercial CFD code and investigated numerically. The multiphase flow in the strait is analyzed and also oil spill is simulated for the same model. During the analyses, the currents in the strait and the sheer force caused by the wind are taken into account

Keywords
