Abstract

The current paradigm for understanding of power and energetics in swimming and flying relies exclusively on the consistent potential theories to analyze the physics qualitatively as well as the observations and measurements to visualize the flow so as to support the theories. We propose a new paradigm of simulation-based biological fluid dynamics to digitize and visualize swimming and flying by using a computational mechanical modeling of the biological fluid dynamics through faithful reconstruction of morphology and representation of realistic kinematics of individual object. The baseline for such an integrated computational system involves the morphological modeling, the kinematic modeling, the computational fluid dynamic modeling, and the post-processing for visualization. Here we address some results associated with realistic modeling of undulatory swimming and flapping flight mechanisms and demonstrate the feasibility of the simulation-based biological fluid dynamics.
