The dynamic lift formula fitting for low-speed fin

Anti-rolling Fins play an important role in ocean transportation with explicitly military objectives. But under the condition of low speed, fin has many disadvantages. In order to optimize the low-speed anti-rolling fin, in this paper, first of all, analyze the hydrodynamic force of low-speed anti-rolling fin in the water. Second, anti-rolling fin simulation analysis are carried out under the condition of low speed by using computational fluid dynamics simulation software FLUENT, and use the MATLAB to fit out of the low speed dynamic lift formula of anti-rolling fin. Research shows that the fitting of anti-rolling fin dynamic lift formula can very kindly response active flapping process in low speed sea condition.
