Stack Gas Investigation for a Dock Landing Ship (LSD 41) Represented by Model 5380,

Abstract

Model experiments were conducted to determine the influence of the air flow around the ship on the exhaust gas plume from the main and auxiliary stacks of a new class of LSD. Observations and photographs were made of a dye and water mix representing the exhaust gases. Stack heights as well as various exhaust gas velocity to wind velocity ratios were investigated at various headings. The results of the experiments indicate that at most headings if the velocity ratio is 3.0 or above, the exhaust gases clear the turbulent zone and the superstructure of the model. (Author)
