Numerical Self-Propulsion Assessment of a Generic Submarine Model at Various Forward Speeds
Journal of Eta Maritime Science, 2021 In this study, we use computational fluid dynamics (CFD) to investigate the self-propulsion characteristics of a submarine model. Predicting a marine vehicle’s self-propulsion features, and as a result, determining the thrust force required to drive the ...

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

Numerical model of self-propulsion in a fluid [PDF]
Journal of The Royal Society Interface, 2005 We provide initial evidence that a structure formed from an articulated series of linked elements, where each element has a given stiffness, damping and driving term with respect to its neighbours, may ‘swim’ through a fluid under certain conditions. We derive a Lagrangian for this system and, in particular, we note that we allow the leading edge to ...

A minimal robophysical model of quadriflagellate self-propulsion [PDF]
Bioinspiration & Biomimetics, 2021 Abstract Locomotion at the microscale is remarkably sophisticated. Microorganisms have evolved diverse strategies to move within highly viscous environments, using deformable, propulsion-generating appendages such as cilia and flagella to drive helical or undulatory motion. In single-celled algae, these appendages can

Tractionless Self-Propulsion of Active Drops [PDF]
Physical 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 ...

Motility and Self-propulsion of Active Droplets
, 2023 In the last few years, self-motile droplets have attracted the attention of scientists from different fields ranging from applied biology to theoretical physics, because of their promising technological applications and important biological implications. In this chapter we review the state of the art of the research on active droplets with a particular
