Swimming patterns of zoospores
… concentrative phenomena: chemotaxis and bioconvection.<br/>In this thesis we investigate the mechanics and implications of zoospore auto-aggregation behaviour using an interdisciplinary approach that combines continuum mathematical modelling with laboratory experimental work. We …

Sensitivity analysis on steady bionanofluid boundary layer flow
… most sensitive to the Lewis number whereas the bioconvection Péclet and Schmidt numbers are the key drive parameters to the local density of motile microorganism. The theoretical study that comes with numerical results serve as an initial guideline or reference for future experimental studies …

Multi-Scale Probing of Colloidal Sedimentation Dynamics in Active Suspensions
… is associated with the development of complex bioconvection patterns. Overall, this dissertation illuminates the intricate interplay between microorganisms and particles in the presence of gravity, revealing nontrivial effects.

Gaining New Insights into Spatiotemporal Chaos with Numerics
… the pattern wavelength. Finally, we analyzed bioconvection which occurs as the result of the collective behavior of a suspension of swimming microorganisms. We developed a series of simulations to capture the gyrotactic pattern formation of the swimming algae. The results can be compared with …

Pattern formation and hydrogen production in suspensions of swimming green algae
… behaviour. Firstly, the phenomenon of bioconvection is explored, where suspensions of motile microorganisms that are denser than the fluid in which they swim spontaneously form concentrated aggregations of cells that drive fluid motion, forming intricate patterns. The cells considered …

Understanding the eco-evolutionary dynamics underpinning changes in air-liquid interface biofilms in radiating populations and multi-species communities
… displacement including Brownian motion and bioconvection currents which otherwise would move aerotaxic wild-type cells away from the high-O2 region. WS mutant cells also possess an additional mechanism to associate and penetrate the A-L interface, where the production of additional …
