Alignment-Induced Self-Organization of Autonomously Steering Microswimmers: Turbulence, Vortices, and Jets
Segun Goh, Elmar Westphal, Roland G. Winkler +1
Systems of motile microorganisms exhibit a multitude of collective phenomena, including motility-induced phase separation and turbulence. Sensing of the environment and adaptation…
HTMPC: A heavily templated C++ library for large scale particle-based mesoscale hydrodynamics simulations using multiparticle collision dynamics
Elmar Westphal, Segun Goh, Roland G. Winkler +1
We present HTMPC, a Heavily Templated C++ library for large-scale simulations implementing multi-particle collision dynamics (MPC), a particle-based mesoscale hydrodynamic simulati…
Active turbulence in microswimmer suspensions -- the role of active hydrodynamic stress and volume exclusion
Kai Qi, Elmar Westphal, Gerhard Gompper +1
Microswimmers exhibit an intriguing, highly-dynamic collective motion with large-scale swirling and streaming patterns, denoted as active turbulence -- reminiscent of classical hig…
Enhanced rotational motion of spherical squirmer in polymer solutions
Kai Qi, Elmar Westphal, Gerhard Gompper +1
The rotational diffusive motion of a self-propelled, attractive spherical colloid immersed in a solution of self-avoiding polymers is studied by mesoscale hydrodynamic simulations.…
Clustering of microswimmers: Interplay of shape and hydrodynamics
Mario Theers, Elmar Westphal, Kai Qi +2
The spatiotemporal dynamics in systems of active self-propelled particles is controlled by the propulsion mechanism in combination with various direct interactions, such as steric…
Modeling a spheroidal microswimmer and cooperative swimming in thin films
Mario Theers, Elmar Westphal, Gerhard Gompper +1
We propose a hydrodynamic model for a spheroidal microswimmer with two tangential surface velocity modes. This model is analytically solvable and reduces to Lighthill's and Blake's…
From local to hydrodynamic friction in Brownian motion: A multiparticle collision dynamics simulation study
Mario Theers, Elmar Westphal, Gerhard Gompper +1
The friction and diffusion coefficients of rigid spherical colloidal particles dissolved in a fluid are determined from velocity and force autocorrelation functions by mesoscale hy…
