The dispersion of exhaust smoke is affected by a large number of parameters such as efflux velocity and temperature of smoke, level of turbulence, wind velocity and direction, geometry of the structures on ship’s deck etc. For this reason, Analyzing of the dispersion of exhaust smoke from ship stack is really complex. Traditionally, the behavior of the exhaust gases by using scale models in wind tunnels can be investigated. In nowadays, however, as a result of technological advances in numerical computational methods and computers, dispersion of the exhaust gases from Marine ship’s stack can be calculated and high performance funnels of the ship can be designed during pre-design phase. While cruising, ship has a boundary layer. In the sailing ships, these harmful emissions from funnel and high exhaust temperature affects the electronic devices in the ship’s deck and also the health of the crew in the deck. In this study, as a result of this literature review of this topic, a short summary of these studies will be presented.
