  • Ship Exhaust Characteristics

    Hello everyone,

    I am working in the field of emission modeling and recently started to investigate ship plumes. There are several different models existing for the calculation of plume rise and I'd like to adapt them to ship stacks. I would like to know some general range for exhaust velocity and temperature at the stack as well as typical diameters of ship stacks, especially for large vessels like container ships or cruise ships. If some of you knows that and/or can provide me with a good reference, I would be very thankful.

    From what I know, the general range for the exhaust gas velocity is maintained about 35m/sec to 50m/sec at specified MCR. As for the temperature of the ship’s stack, it can reach up to 300-400 deg. C. A funnel would be 5 of 11 feet in diameter and an elliptical outer casing 6 having major and minor diameters of 16 feet 6 inches and 14 feet 6 inches.
