FIG. 1.

Snapshots of bacterial (left) and oxygen (right) concentration fields at statistical steady state for different film thicknesses: (a) and (b) L = 100 μm, (c) and (d) L = 300 μm, and (e) and (f) L = 600 μm (enhanced online). [URL: http://dx.doi.org/10.1063/1.4752764.1]10.1063/1.4752764.1

FIG. 2.

Vertical profiles for different film thicknesses L: (a) bacterial concentration c(z)/n, (b) oxygen concentration s(z), (c) oxygen consumption K(z)/n, and (d) rms of the vertical fluid velocity Δu z (z). Simulation results (symbols) are compared to the base state (lines).

FIG. 3.

Base-state profiles of (a) active stress component , and (b) aerotaxic drift U d /U 0. (c) Base-state values of β and Pe b and corresponding regimes in simulations, compared to the marginal stability curve βcrit of Kasyap and Koch.23 The data points correspond to values of L in the range 50–600 μm.
