Fluid flows shaping organism morphology
A dynamic self-organized morphology is the hallmark of network-shaped organisms like slime moulds and fungi. Organisms continuously re-organize their flexible, undifferentiated body plans to forage for food. Among these organisms the slime mould P. polycephalum has emerged as a model to investigate how organism can self-organize their extensive networks and act as a coordinated whole. Cytoplasm...
متن کاملShaping Behaviour with Adaptive Morphology
Robots which exploit their embodiment promise to be more robust, energy-efficient and adaptable. However, the majority of systems designed in this way are only capable of exploiting their embodiment when performing a single task in a single environment. For such robots to be capable of adapting to a range of tasks or environments, they must be capable of adjusting their morphology on-line and h...
متن کاملNonstandard Discretizations for Fluid Flows
The Immersed Boundary Method (IBM) has been designed by Peskin for the modeling and the numerical approximation of fluid-structure interaction problems and it has been successfully applied to several systems, including the simulation of the blood dynamics in the heart; see [1]. In the IBM the Navier-Stokes equations are considered everywhere and the presence of the structure is taken into accou...
متن کاملNonstandard Discretizations for Fluid Flows
Computational Fluid Dynamics is a field on the interface between Numerical Analysis, Computational Science, Physics and Engineering. It underwent an intensive development primarily because of the needs of aeronautics, nuclear physics and engineering, geophysics, chemical and automotive engineering etc., and the rapid development of fast computers. The major efforts are concentrated on the effic...
متن کاملComputations of multi-fluid flows
Full numerical simulations of three-dimensional flows of two or more immiscible fluids of different densities and viscosities separated by a sharp interface with finite surface tension are discussed. The method used is based on a finite difference approximation of the full Navier-Stokes equations and explicit tracking of the interface between the fluids. Preliminary simulations of the Rayleigh-...
