Complex and time-dependent long-range hydrodynamic flows around a spherical active particle of radius $a$ generated by a simple linear combination of time-dependent stresslet, potential dipole and septlet. Streamlines show the direction of the flow while the background color represents the natural logarithm of the strength of the flow. The red dot indicates the approximate position of the stagnation point. These flow fields capture the essential features of experimentally measured flow fields around a swimming Chlamydomonas [Guasto et al., Phys. Rev. Lett., 2010]. The inset shows the variation of the potential dipole and the stresslet; the blue line shows the overall variation, while the red square shows the current value.
