Extended Data Fig. 7: Streamlines generated by a pair of model Stentor individuals.

(a) Fluid flows generated by a Stentor pair, modeled as a pair of regularized Stokeslets of strengths F1 and F2 respectively near a wall with force ratio F1/F2 = 1, inter-Stentor separation distance Δ = 2 (left) and Δ = 0.5 (right) (b) Force ratio F1/F2 = 2 and inter-Stentor separation distances Δ = 2 (left), and Δ = 0.5 (right). Top row: flow streamlines. Bottom row: downward velocity component of the flow velocity determined along the horizontal line z = 1.25H.
