WebNov 25, 2024 · The rotation time t rot of a single RBC in simple shear flow is the inverse of the rotation frequency, which varies linearly with the shear rate . We apply fast Fourier transform to a time series window of selected material points on each particle, as shown in fig. S3, to calculate the corresponding frequency spectrum and the rotation period.
