Experimental Study of Air Flow over a 2% Scale Model of the FFG-7 Including Simulation of Gas Turbine Inlet Flow

Abstract

Flow visualization studies were conducted on the gas turbine inlets on the FFG-7. Smoke, helium bubbles, and tufts were used. Flows were investigated at 0 and 10 degrees pitch and several yaw angles from 0 to 225 degrees at 10 to 25 knots wind-over-deck speed. The present gas turbine inlet arrangement and several modifications were tested and it was shown that flow at the inlet area is affected by the ship configuration bridge structure and bow. The bow effects at the inlet become significant on the down wind side inlet when winds are quartering off the bow.
