Ventilations, Bell-mouthed Or Cowl
Bell-mouthed or cowl ventilations are devices used on ships to provide ventilation to enclosed spaces such as engine rooms, cargo holds, and accommodation areas. They consist of a hood or cowl-shaped cover that is placed over an opening in the ship's structure. The cowl is designed to catch the wind and create a vacuum that draws air out of the enclosed space. This creates a flow of fresh air into the space, which helps to remove heat, fumes, and other pollutants. Bell-mouthed or cowl ventilations are an important safety feature on ships, as they help to prevent the buildup of dangerous gases and ensure that crew members have access to fresh air.
