Duality in Disk Induced Flows
We introduce a condition that establishes a duality known from Delaunay triangulations and Voronoi diagrams for diagrams associated with a class of dynamical systems defined via a set of disks in the plane. Under this condition the maximum geometric and worst case algorithmic complexities of the latter diagrams decrease. The condition is natural in the sense that it is automatically fulfilled b...
متن کاملPlankton blooms induced by turbulent flows.
Plankton play an important role in the ecology of the ocean and the climate because of their participation in the global carbon cycle at the base of the food chain. However, damaging plankton blooms can sometimes occur and are initially characterized by sudden transient increases in the phytoplankton population. They are thought to be driven by several effects, such as seasonal variations in te...
متن کاملGrowth-induced mass flows in fungal networks.
Cord-forming fungi form extensive networks that continuously adapt to maintain an efficient transport system. As osmotically driven water uptake is often distal from the tips, and aqueous fluids are incompressible, we propose that growth induces mass flows across the mycelium, whether or not there are intrahyphal concentration gradients. We imaged the temporal evolution of networks formed by Ph...
متن کاملRoughness induced boundary slip in microchannel flows.
Surface roughness becomes relevant if typical length scales of the system are comparable to the variations as it is the case in microfluidic setups. Here, an apparent slip is often detected which can have its origin in the misleading assumption of perfectly smooth boundaries. We investigate the problem by means of lattice Boltzmann simulations and introduce an "effective no-slip plane" at an in...
متن کاملSingularity induced exterior and interior Stokes flows
In this paper, the two-dimensional Stokes flow inside and outside a circular cylinder induced by a pair of line singularities ~rotlet and stokeslet! is studied. Analytical solutions for the flow field are obtained by straightforward application of the Fourier method. The streamline patterns are sketched for a number of special cases where the cylinder is either stationary or rotating about its ...
