FIG. 7.

(a) State diagram for the classifications of “isolated” and “influenced” by using a threshold of the influence factor (here: ${\psi }_{\mathit{M}\mathit{i}\mathit{s}}=0.97$) as a function of angle, cell distance, and cell shape. The flat ellipsoid can be considered as isolated for all the angles and distances. All other cell shapes have regions influenced by the rotating cell. (b) shows the influence factor ${\psi }_{\mathit{M}\mathit{i}\mathit{s}}$ depending on the rotating angle $\alpha$ and the flow velocity $v$. The stationary cell is more influenced if located both anteriorly and posteriorly of the rotating cell, whereas the latter is more dominant. Additionally, in the latter case, the influence on the stationary cell increases with increasing velocity ($\alpha \in [150°,\hspace{0.17em}210°]$).
