Resistance Reduction Studies by Means of Increasing the Beam with Waterline Parabolization
It
has been more than a decade since Calisal et al. (2002) proposed the concept of
reduction of the resistance by increasing the beam. Although this is a
controversial concept compared to the traditional approach which adopts that the
coefficients of residual resistance vary with the beam to the power of 2. The authors,
during the course of resistance reduction studies, have disclosed that the new
present concept has the ability to reduce the resistance for the Froude number
interval of 0.2 – 0.4. Accordingly, a review of the authors’ previous work is
presented here from the resistance point of view as well as from the seakeeping
point of view. Moreover, the production cost due to increasing the beam is also
examined and explained. The studies presented include mathematical,
computational and experimental results.
