Self-propulsion through symmetry breaking [PDF]

open access: yesEPL (Europhysics Letters), 2013
In addition to self-propulsion by phoretic mechanisms that arises from an asymmetric distribution of reactive species around a catalytic motor, spherical particles with a uniform distribution of catalytic activity may also propel themselves under ...

ON SELF-PROPULSION ASSESSMENT OF MARINE VEHICLES

open access: yesBrodogradnja, 2018
Estimation of ship self-propulsion is important for the selection of the propulsion system and the main engine so that the ship can move forward with the required speed.

Phoretic self-propulsion at finite P\'eclet numbers [PDF]

open access: yesJournal of Fluid Mechanics, 2014
Phoretic self-propulsion is a unique example of force- and torque-free motion on small scales. The classical framework describing the flow field around a particle swimming by self-diffusiophoresis neglects the advection of the solute field by the flow ...

Numerical prediction method of shafting power characteristics of free self-propelled ship in waves

open access: yesZhongguo Jianchuan Yanjiu, 2022
ObjectiveTo investigate ship power characteristics and the difference between the towing model and self-propulsion model for ship motion response in waves, numerical simulations of ship self-propulsion performance in waves are carried out. MethodsIn this

Tractionless Self-Propulsion of Active Drops [PDF]

open access: yesPhysical Review Letters, 2019
We report on a new mode of self-propulsion exhibited by compact drops of active liquids on a substrate which, remarkably, is tractionless, i.e., which imparts no mechanical stress locally on the surface. We show, both analytically and by numerical simulation, that the equations of motion for an active nematic drop possess a simple self-propelling ...

Phoretic self-propulsion at large Péclet numbers [PDF]

open access: yesJournal of Fluid Mechanics, 2015
We analyse the self-diffusiophoresis of a spherical particle animated by a non-uniform chemical reaction at its boundary. We consider two models of solute absorption, one with a specified distribution of interfacial solute flux and one where this flux is governed by first-order kinetics with a specified distribution of rate constant.

Self-propulsion of liquid marbles: Leidenfrost-like levitation driven by marangoni flow [PDF]

open access: yes, 2015
Self-propulsion of liquid marbles filled with aqueous alcohol solutions and placed on a water surface is reported. The characteristic velocity of the marbles is ca. 0.1 m/s.

Self-Propulsion Strategies for Artificial Cell-Like Compartments. [PDF]

open access: yesNanomaterials (Basel), 2019
Reconstitution of life-like properties in artificial cells is a current research frontier in synthetic biology. Mimicking metabolism, growth, and sensing are active areas of investigation; however, achieving motility and directional taxis are also challenging in the context of artificial cells. To tackle this problem, recent progress has been made that
