How efficient is towing a cargo by a micro-swimmer?
Oren Raz, Alexander M. Leshansky
We study the properties of arbitrary micro-swimmers towing a passive load through a viscous liquid. The simple close-form expression for the dragging efficiency of a general micro-…
A geometric theory of swimming: Purcell's swimmer and its symmetrized cousin
J. E. Avron, O. Raz
We develop a qualitative geometric approach to swimming at low Reynolds number which avoids solving differential equations and uses instead landscape figures of two notions of curv…
A Comment on "Optimal Stroke Patterns for Purcell's Three-Link Swimmer"
O. Raz, J. E. Avron
For large enough aspect ratio, we find better stroke patterns then the patterns proposed by D. Tam and A.P.Hosoi in their letter to PRL "Optimal Stroke Patterns for Purcell's Three…
Swimming, Pumping and Gliding at low Reynolds numbers
J. E. Avron, O. Raz
Simple, linear equations relate microscopic swimmers to the corresponding gliders and pumps. They have the following set of consequences: The swimming velocity of free swimmers can…
