In particular, it focuses on mesoscale turbulence, a state observed in microswimmer suspensions, which is characterized by the emergence of dynamic vortex patterns. The first major contribution concerns the bottom-up derivation of a frequently used continuum model of mesoscale turbulence from a set of particle-resolved stochastic equations. Utilizing the model, mesoscale turbulence is shown to induce nontrivial transport properties including a regime of optimal diffusion. The thesis then explores possible strategies of control. One of these relies on an external field that leads to stripe-like structures and can even suppress patterns entirely. The other involves geometric confinement realized by strategically placed obstacles that can reorganize the flow into a variety of ordered vortex structures. The turbulence transition inside an obstacle lattice is shown to have an intriguing analogy to an equilibrium transition in the Ising universality class. As a whole, this thesis provides important contributions to the understanding and control of turbulence in active fluids, as well as outlining exciting future directions, including applications. It includes a substantial introduction to the topic, which is suitable for newcomers to the field.\u003c\/p\u003e\n                            \n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783031676352\"\u003e\u003ch3\u003eThe Impact of Translational and Rotational Constraints on Pattern Formation in Microswimmer Suspensions\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783031676383\"\u003e\u003ch3\u003eThe Impact of Translational and Rotational Constraints on Pattern Formation in Microswimmer Suspensions\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Hardcover - 9783031676352","offer_id":50200472289605,"sku":"9783031676352","price":235.39,"currency_code":"EUR","in_stock":true},{"title":"Softcover - 9783031676383","offer_id":57949203628357,"sku":"9783031676383","price":235.39,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2ce91bff-a834-4f7c-aa73-c71ca18a5bac.jpg?v=1778817919","url":"https:\/\/shop.autorenwelt.de\/products\/controlling-mesoscale-turbulence-von-henning-reinken","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
