Study on Surface Pressure Distribution of Fishing Vessel

Abstract

In this paper a method of composite expansion in singular perturbation problem is applied to the calculation of the pressure and velocity distributions on ship hulls. An uniformly valid solution of the fluid motion about a ship moving forward steadily is obtained through the matching and combining process between the inner and the outer solutions of asymptotic expansion. The results of the calculation of the surface pressure and the crosssectional sinkage force distribution of a fishing vessel are compared with the inner solution and also with measurments.
