Comparison of the probability distribution of the areal density of bacteria between the experiment and the simulation. Blue triangles indicate experimental results of 0 and 1Â h. Colored lines and red circles indicate the numerical results. a Effect of \({\alpha }_{w}\) on the accumulation of cells near the wall, where \({\alpha }_{w}\) is a dimension-free parameter indicating the ratio of ensemble-averaged bacterial velocity away from the wall to that toward the wall. b Effect of \({\text{Pe}}\) on the bulk gradient cell distribution. c The least-square fit of the numerical results with the experimental results (\({\text{Pe}}=0.018, {\alpha }_{w}=0.14, {r}^{2}=0.92\))
