The hydrodynamics of swimming microorganisms
Note that the “body” includes appendages such as the cilia covering a Paramecium or the helical flagella of E. coli.
The hydrodynamics of swimming microorganisms
For example, to model the locomotion of ciliates such as Opalina and Paramecium, Lighthill introduced the “envelope model,” in which the tips of the beating cilia that cover the cell body are represented by propagating surface waves [89, 90, 91].
The hydrodynamics of swimming microorganisms
Detailed experiments were also carried out to study hydrodynamic interactions between the protozoan Paramecium [177].
