We simulate the self-propulsion of devices in a fluid in the regime of low Reynolds numbers. Each device consists of three bodies (spheres or capsules) connected with two damped harmonic springs. Sinusoidal driving forces compress the springs which are resolved within a rigid body physics engine. The latter is consistently coupled to a 3D lattice Boltzmann(More)
– We compare fully-resolved, 3D lattice Boltzmann (LB) simulations of a three sphere microswimmer to analytical calculations, and show thereby that (i) LB simulations reproduce the motion very well in the Stokes regime, and (ii) the swimmer exits this regime at Reynolds numbers Re ∼ 10 −2 , significantly lower than previously realised. Below this Re value(More)
