Figure 12


Fig. 12. Trends in surge and heave forces with respect to frequency, maximum angular deflection, fin aspect ratio and specific wavelength. In each panel, the parameter 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). The gray area shows the root mean square deviation of the force for one cycle. (A) Simulation Set 1, (B) simulation Set 2, (C) simulation Set 3 and (D) simulation Set 4; surge to heave crossover is at {lambda}/Lfin=1.5. The estimated error based on grid sensitivity and domain length sensitivity is 10% of the mean value.
