Numerical methods for RANSE simulations of a self-propelled fish-like body

Self-propelled Janus particles in a ratchet: numerical simulations.

Brownian transport of self-propelled overdamped microswimmers (like Janus particles) in a two-dimensional periodically compartmentalized channel is numerically investigated for different compartment geometries, boundary collisional dynamics, and particle rotational diffusion. The resulting time-correlated active Brownian motion is subject to rectification in the presence of spatial asymmetry. W...

Performing self propelled simulations of a kayak, using a Body-force paddle model

Understanding the interactions between a hull and a propeller is a common problem naval architects have to solve to provide efficient powering solutions. The world of elite sport is becoming increasingly scientific in a similar drive for increased performance. To allow a kayak’s hull and paddle to be optimised, their interactions have to be considered to provide a realistic race scenario. It is...

Direct Numerical Simulation of Self - Propelled Swimming of 3 D Bionic Fish School † Chui

Direct numerical simulation of self-propelled swimming of three dimensional bionic fish and fish school in a viscous flow in a tank are investigated. The swimming rule and the profile of 3D fish from previous experimental measurements of living fish are used in the study. A parallel software package for the 3D moving boundary problem is obtained, which combines the adaptive multi-grid finite vo...

Numerical investigation of a fleet of self-propelled AUVs

This paper investigates the influence of the propeller on the drag of twin self-propelled AUVs, firstly, to examine the fleet performance for various propulsive conditions of leading and following AUV and, secondly, to study the parametric influence of transverse separations and longitudinal offsets on the fleet’s drag. A series of CFD RANS-SST simulations have been performed at the Reynolds Nu...
