Figure 15


Fig. 15. Scaling of the surge force. Computational results are shown with a dot, and the curve fit with a black line. The error is defined as the root mean square error in mN for each curve fit. Estimation of surge force for a stationary fin using eqn 11 in Lighthill and Blake (Lighthill and Blake, 1990) are show in gray. In each panel, the factor shown on the x-axis is varied while keeping other parameters of the baseline case constant ({theta}max=30 deg., f=2 Hz, {lambda}/Lfin=0.5, hfin/Lfin=0.1). (A) linear fit of the natural log-transformed data for frequency (Hz), (B) linear fit of the natural log-transformed data for {theta}max (deg.) (C) linear fit of the log-transformed data for hfin/Lfin, (D) Curve fit of surge force as a function of specific wavelength.
