Over the years, these funnels which were tallest structure on ships are no more the tallest structures and are now dominated by masts which have various electronics and antenna’s. This change has resulted in to smoke ingress problem. The gas turbine intake is located close to the funnels. The smoke entrapped in the wake of masts gets sucked in the intake of the turbine thereby raising the temperature at the intake resulting in lowering the efficiency of gas turbine. The flow and performance characteristics for a simplified model are carried out by providing opening in mast structure of different shapes to see the effect on smoke ingress problem.
