Near-field hydrodynamics of beating flagella. (a–c) Axial u (left) and lateral v (right) flow as a function of beat cycle for a typical (a) mstg, (b) cw15, and (c) cc125 cell. The red solid curve is the prediction from hydrodynamic modeling (BEM). (d and e) Comparison of MAE of BEM predictions for (d) axial flows MAEu and (e) lateral flows MAEv, for mstg, cw15, and cc125 strains from left to right, respectively. The data represented are from within ∼20 μm of a beating cell , or the lightly shaded areas in Fig. 5. The sample size for (d) and (e) is for each strain. To see this figure in color, go online.
