What is it about?
The effects of efflux velocity, operational conditions, stack geometry, and buoyancy on the exhaust dispersion for a generic frigate are investigated numerically. The conservation of energy, momentum, mass, species, and turbulence equations have been solved using the finite volume method.

Why is it important?
The effects of the operational conditions (slow ahead, half ahead, full ahead, and backward cruising operations), design parameters (stack geometry, efflux velocity, and exhaust temperature) and buoyancy on the exhaust smoke dispersion of a generic frigate are presented and discussed. The validation study shows that there is a good agreement between the numerical results and experimental data obtained from the wind tunnel tests. Namely, the numerical model predicts the downwash phenomena and plume rise correctly.
Perspectives
It is understood that the dispersion of exhaust smoke is an important phenomenon and it should be considered in the preliminary design stage of the ships.
