RESEARCH IN RESISTANCE AND PROPULSION PART 2: STREAMLINE CALCULATIONS FOR SINGULARITIES DISTRIBUTED ON THE LONGITUDINAL CENTER PLANE

A computer program was written for the problem of determining the hull form produced by a given singularity distribution defined on the longitudinal, center plane. The program is based on the Runge-Kutta fourth order method in solving the differential equations of the stream lines. Results indicate the number of subdivisions required to meet a specified degree of accuracy. The program admits rather general forms of the singularity distribution functions. A computer program was also written for the purpose of determining the two-dimensional singularity distribution for a given shape of the waterline. Applied to a Series-60 set of lines the three-dimensional effect of truncation has been investigated and found to be substantial.(Author)
