Figure 4
Normalized viscous drag coefficients of individual M. gryphiswaldense cells as a function of bacterial dimensions. The rotational (a) and translational (b) viscous drag coefficients were both calculated with Stokesian dynamics and with a Boundary Integral Method. Shown are the mean values of both methods, which deviate only negligibly from each other. The viscous drag coefficients are normalized by the viscosity of the medium η and plotted as a function of the end-to-end length L ee of the bacteria. The amplitude A of the bacteria is indicated by the color of the data points. For comparison purposes, the normalized viscous drag coefficients of cylinders with various diameters are also shown.
