Microswimmers in turbulent fluid flow of Taylor-scale Reynolds number Re = 21 dataset

The data includes the trajectories and the swimming velocities of individual microswimmers embedded in a turbulent fluid flow of Taylor-scale Reynolds number \(Re_{\lambda} = 21\) .

The net swimming velocity of a microswimmer is the sum of the intrinsic swimming velocity and the fluid velocity. The intrinsic swimming velocity is dictated by the swimming parameters, that is, the swimming speed \(v_s\) and the reorientation time \(B\).

Different values of swimming parameters are explored.
