Computational Biological Fluid Dynamics: Digitizing and Visualizing Animal Swimming and Flying

Computational biological fluid dynamics: digitizing and visualizing animal swimming and flying.

Characterized by complex geometry and complicated dynamic process, biological fluid dynamics in swimming and flying is usually of large scale vortex flows with four-dimensional nature, namely, spatial three-dimensional and one-dimensional in time. Conventional theories for understanding power and energetics in swimming and flying rely exclusively on the consistent potential flow formulation in ...

Dynamics and energetics of animal swimming and flying: introduction.

This symposium approaches answers to these questions from multiple directions. Four primary sets of technological developments have come together in the past decade to make it possible to revisit each of these questions in innovative, quantitative ways. These developments are: a) highspeed digital video photography; b) algorithms for rapid analysis of digital images; c) laser based quantitative...

Computational Modeling of Fluid–structure Interaction in Biological Flying and Swimming

Computational Modeling in Biological Fluid Dynamics

A major problem in characterising the locomotion of freely-moving, isolated cells in culture is the large variability between individual cells and the large variation in motile characteristics with time. DRIMAPS (Digitally Recorded Interference Microscopy with Automatic Phase Shifting) is a technique developed at the Randall Institute that overcomes this problem by enabling data from large numb...

Analysis of drafting effects in swimming using computational fluid dynamics.

The purpose of this study was to determine the effect of drafting distance on the drag coefficient in swimming. A k-epsilon turbulent model was implemented in the commercial code Fluent(®) and applied to the fluid flow around two swimmers in a drafting situation. Numerical simulations were conducted for various distances between swimmers (0.5-8.0 m) and swimming velocities (1.6-2.0 m.s(-1)). Dr...
