A New Method for Scaling Submarine Resistance Model Data
Abstract
A new method is presented for obtaining full-scale resistance predictions from model-scale submarine resistance tests. Traditionally, model-scale submarine resistance data is scaled using Froude’s Hypothesis, where the resistance is decomposed into frictional resistance and residual resistance. The frictional resistance is computed from a flat plate friction line formula at both model- and full-scale. The residual resistance coefficient is measured model-scale and is assumed to be independent of Reynolds number. Since the flow is assumed to be turbulent at fullscale, turbulence stimulators are placed at about 5% x/L to trip the flow in the model tests. The parasitic drag from the turbulence stimulators must be measured and subtracted from the model-scale resistance.
