The role of hydrodynamic interaction in the locomotion of microorganisms

摘要: A general Boundary Element Method is presented and benchmarked with existing Slender Body Theory results reflection solutions for the motion of spheres slender bodies near plane boundaries. This method used to model swimming a microorganism spherical cell body, propelled by single rotating flagellum. The such an organism boundary, midway between two boundaries or in vicinity another similar organism, investigated. It found that only small increase (less than 10%) mean speed parallel identical organism. Similarly, minor propulsive advantage (again, less 10% speed) predicted when swims very close (such as microscopic plate (or) coverslip, example). explained terms flagellar derived from ratio normal tangential resistance coefficients body being offset apparently equally significant drag. For toward however, it (assuming its flagellum, relative constant angular frequency) resulting decreases asymptotically approaches boundary.
