The study shows a spatial symmetry breaking in flow patterns, while maintaining temporal symmetry in oscillatory motion.
Importantly, Reynolds numbers were examined, ranging from Re=150 to Re=1000 for stationary conditions, and Re=250 in motion.
Applying a two-dimensional transient model, the Fourier pseudospectral method couples with immersed boundary method for analysis.
Significantly, IMERSPEC offers advantages like spectral accuracy and low numerical diffusion for complex fluid interactions.
