Abstract: The transom stern of a typical merchant ship can be partially submerged in specific loading conditions. at low speed, a dead water may form behind the transom. The dead water region is associated with viscous pressure losses and significant influences the wave pattern and the resistance. Potential codes are sufficient to calculate the wave resistance but cannot predict viscous effects from first principles. Instead they often apply empirical expressions for the viscous resistance. The present work aims to extend an inviscid calculation procedure by an empirical dead water model.
