This seemingly contradicts the fact that a swimmer is force-free and torque-free, i.e. that the net force and torque on the particle vanish. Using different models for mechanical and diffusiophoretic self-propulsion, we demonstrate here that the equations of motion of microswimmers can be mapped onto those of passive particles with the shape-dependent grand resistance matrix and formally external effective forces and torques. This is consistent with experimental findings on the circular motion of artificial asymmetric microswimmers driven by self-diffusiophoresis. The concept of effective self-propulsion forces and torques significantly facilitates the understanding of the swimming paths, e.g. for a microswimmer under gravity. However, this concept has its limitations when the self-propulsion mechanism of a swimmer is disturbed either by another particle in its close vicinity or by interactions with obstacles, such as a wall.</dcterms:abstract> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/39259"/> <dc:creator>Takagi, Daisuke</dc:creator> <dc:creator>Kümmel, Felix</dc:creator> <dc:creator>Wittkowski, Raphael</dc:creator> <dc:contributor>Wittkowski, Raphael</dc:contributor> <dc:contributor>Takagi, Daisuke</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-06-13T12:09:37Z</dc:date> <dcterms:title>Can the self-propulsion of anisotropic microswimmers be described by using forces and torques?</dcterms:title> <dcterms:issued>2015-05-20</dcterms:issued> </rdf:Description> </rdf:RDF>
