Fluid Dynamics of Biomimetic Pectoral Fin Propulsion Using Immersed Boundary Method

Figure 8

Validation and assessment of the numerical method. (a) Results of grid refinement and domain independence study for , , , , , , and case. (b) Comparison of computed drag coefficient on flow past a sphere with previous studies. (c) Comparison of time-averaged drag coefficient for the oscillating cylinder in a free stream with . The solid line represents the results from [53] and the symbols are the data from our IB method using two different time step sizes. (d) Comparison of time-averaged thrust coefficient for the flapping foil with experimental data from [57]. The Strouhal number is fixed at a value of 0.6 and the maximum angle of attack is varied from to .
