Improving Hydrodynamic Model for Zero Speed Bionic Fin Stabilizer

The single analytical method is used in modeling the existing hydrodynamic force model for zero speed fin stabilizers,where the effect of the fin thickness and shape on the hydrodynamic model is ignored during the modeling process and the analysis of the vortex drag is also crude.These problems result in not only more parameters to be determined in the model,but also great difference between the model and the real situation.In view of these problems,the composite method of the numerical and the analytical approaches is used to improve the hydrodynamic force model and its old modeling method in order to make the modified model more exact,and without loss of engineering practicability.Finally,the theoretical calculation value is compared with that from the FLUENT,and the advantages of the modified model and modeling method are demonstrated.
