Active bodies undergo self-propulsive motion in a fluid medium and span a broad range of length and time scales. This report focuses specifically on the motion at high Reynolds number, where inertial forces dominate the fluid dynamics. Many active systems spontaneously self-organize into visually striking structures: fish schooling, birds flocking, and

Abstract The study of an ideal (perfect) fluid-’dry water’, as Richard P Feynman refers to it in the Feynman Lectures in Physics-is a crucial part of fluid dynamics. In the mechanics of solids, the laws of motion can be expressed, in the absence of friction, in terms of conservation laws.

Flows, Hierarchies, Potentials
Environment and Planning A: Economy and Space, 1981This work deals with the analysis of interregional flows. The central idea is the decomposition of the origin–destination flow matrix into the additive weighted sum of basic matrices. Each basic matrix represents an extremal flow which optimizes some objective function corresponding to some extremal tendency acting in the real flow.

A method is presented for calculating potential flows in infinite channels. Given a collection of N sources in the channel and a zero normal flow boundary condition, the method requires an amount of work proportional to N to evaluate the induced velocity field at each source position.

On the Stationary, Potential, Subsonic Flow
Results in Mathematics, 2000Summary: We are concerned with the problem of the stationary, potential, subsonic flow. Firstly, we formulate the mechanical problem and the associated minimization problem with constraints, in a functional space \(W\) endowed with a certain norm. Section 2 contains the main original results.

An investigation is made of some questions pertaining to the stability of potential flow. A formalism due to Eckart is adapted to obtain equations for the perturbations of a known steady potential flow, in a coordinate system defined by the potential function and the stream function.

The potential energy of knowledge flow
Concurrency and Computation: Practice and Experience, 2006AbstractA knowledge flow is invisible but it plays an important role in ordering knowledge exchange when working in a team. It can help achieve effective team knowledge management by modeling, optimizing, monitoring, and controlling the operation of knowledge flow processes. This paper proposes the notion of knowledge energy as the driving force behind
