From: Re-entrant bimodality in spheroidal chiral swimmers in shear flow

Rescaled orientational PDF (normalized by total concentration in the channel) of spheroidal chiral swimmers of aspect ratio λ = 4 (corresponding, e.g., to a = 2 μm and b = 0.5 μm) on the top wall of the channel (i.e. at non-dimensional vertical coordinate y = +1), when they exhibit angular speeds of different magnitudes and directions, including the non-chiral case (Γ = 0). (Dimensionless) system parameters, as appearing in the governing equation 1, are: Pe s = 0.25, Pe f = 25, and ξ = 0.1.
