Abstract:

Prior research has investigated partially ventilated steady transom flows for a family of hulls that have a common fore-body with varying after-bodies. This project expands the investigation into unsteady transom flow elevations two of the five different transom configurations, including a round bilge and a deep-vee sections. A common wave profile was used for the experiments and wave elevations were measured at 24 different positions within the towing tank.. High definition video was used to capture the flow elevations for a range of speeds. This report presents the findings in terms of the transom Froude number and ventilation factors.
