要約

A new method of streakline tracing for time-periodic flow has been developed and applied to the visualization processing of biofluids induced by fluid-structure interactions in biomechanics. This method takes advantage of the time periodicity of the forced oscillation biofluids by decomposing the computed velocity field into a Fourier series. Therefore, calculation of streaklines can be implemented in the post-processing separately from the solution to the Navier-Stokes (NS) equations, and hence large reduction of computing time and memory for storage requirements is achieved. The method is formulated and executed in computational space and is capable of dealing with complex external flows around swimming and flying animals with moving/deforming boundaries.
