(Color online) (a) Trajectory and (b) temporal evolution of orientation angle α for squirmers of β = 0 and 7 at Re = 1 and initially located at α0 = −π/4, h0 = 2. Gray area and the black line in (a) show the area inside which the gap between the squirmer and the wall is less than one mesh size of Δ = 0.1 and Δ = 0.05, respectively.
