A Brief Review on Examination of Exhaust Gas Dispersion on Naval Ships
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. gazlarının dağılımının hesabı karmaşıktır. Geleneksel olarak egzoz gazların davranışı ölçekli modeller kullanılarak rüzgâr tünellerinde incelenebilir. Günümüzde ise sayısal hesaplama metotlarındaki ve bilgisayarlardaki teknolojik gelişmeler sonucunda egzoz gazlarının dağılımı daha kolay bir şekilde hesaplanabilmekte ve yüksek performansa sahip gemi bacaları dizayn edilebilmektedir. Gemiler seyir halinde iken bir sınır tabakaya sahiptir. Egzoz gazları üst binada bulunan sistemlere zarar verebilmekte ve aynı zamanda güvertede çalışan personelin sağlığını da etkilemektedir. Bu çalışmada; konu üzerinde yapılan çalışmaların incelenmesi sonucunda kısa bir literatur özeti sunulacaktır
