STACK DESIGN TECHNOLOGY FOR NAVAL AND MERCHANT SHIPS

This paper discusses design techniques for surface ship stack casings and exhaust duct terminals. The discussion treats both naval combatant and auxiliary vessel stack designs, as well as commercial stack configurations. The traditional engineering problems unique to stack design are described. These include naval architectural problems associated with topside arrangements and superstructure design as well as safety and esthetic considerations associated with entrainment of the smoke plume in downwash passing over ship's decks. The experimental data base for the design practices used by the U.S. Navy is presented and discussed. Examples of unique contributions to the state-of-the-art are presented. Analytical theory and procedures are descriged in detail. These include design guidance for selecting the height, shape, location of the stack, and techniques or estimating the downward plume gas temperatures and trajectories.
