Limiting propulsion of ionic microswimmers [PDF]
, 2023 Self-propulsion of catalytic Janus swimmers in electrolyte solutions is induced by inhomogeneous ion release from their surface. Here, we consider the experimentally relevant cases of particles which emit only one type of ions (type I) or equal fluxes of cations and anions (type II).

Swimmers’ Effective Actions during the Backstroke Start Technique
Sensors, 2023 The analysis of the external forces of swimming starts has revealed how swimmers propel themselves out of the block, but data should be properly interpreted to fully understand force-generation mechanisms.

Propulsive Capability of an Asymmetric GDM Propulsion System [PDF]
42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2006 *† The role of the ambipolar potential in the propulsive capability of the Gasdynamic Mirror (GDM) has been studied previously. The electrostatic potential arises as a result of the initial rapid escape of the electrons due to their small mass, leaving behind an excess of ions and creating a positive electric potential that slows down the electron ...

Numerical Study on Fluid Dynamic Characteristics of a Cross-Flow Fan
Journal of Marine Science and Engineering, 2023 This paper focuses on the application of a cross-flow fan (CFF) to generate propulsion for a submersible aircraft with a flying wing configuration. A numerical method is established to simulate the CFF operating both in the air and underwater. This paper
