A Model for Intracranial Hydrodynamics

2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005
This paper presents a model for simulation of intracranial fluid dynamics. The intention is to show how to build a model for this biomedical system by using general techniques known to control engineers. By employing first order principles (like conservation of mass, ...) and constitutive equations, the ;biological' control loops are interpreted in a ...

Hydrodynamic model in isospin channels

Physical Review Letters, 1987
The Steinwedel-Jensen hydrodynamic model is generalized to study isovector collective modes excited in charge-exchange reactions. Results are given for the energy splittings between the different isospin components of the giant dipole and monopole resonances recently observed in (p,n) and (..pi../sup +- /,..pi../sup 0/) reactions. The quenching of the .

Thermodynamics and Hydrodynamics for a Modeled Fluid

Journal of Mathematical Physics, 1972
This article presents a general study of a two-dimensional fluid model with microscopic discrete velocities. The rather unusual properties of this model lead to precise thermodynamical laws. The Navier-Stokes hydrodynamical equations are obtained, which contain a transport coefficient given by a Green-Kubo integral, and it is shown that this integral ...

Hydrodynamics of bacterial colonies: A model

Physical Review E, 2003
We propose a hydrodynamic model for the evolution of bacterial colonies growing on soft agar plates. This model consists of reaction-diffusion equations for the concentrations of nutrients, water, and bacteria, coupled to a single hydrodynamic equation for the velocity field of the bacteria-water mixture.

Hydrodynamic model for drying emulsions

Physical Review E, 2015
We present a hydrodynamic model for film formation in a dense oil-in-water emulsion under a unidirectional drying stress. Water flow through the plateau borders towards the drying end leads to the buildup of a pressure gradient. When the local pressure exceeds the critical disjoining pressure, the water films between droplets break and the droplets ...

Hydrodynamical models of elliptical galaxies

Celestial Mechanics, 1988
Hydrodynamical models of elliptical galaxies can be obtained by means of Jeans’equations (see for example Ortega and de Freitas Pacheco, 1986). Following this approach, we consider a mass distribution in steady state which approximates de Vaucouleurs’ r1/4 law, and assume the principal axes of the velocity distribution to be parallel to unitary vectors

A hydrodynamic model of a permeable tubule

Journal of Theoretical Biology, 1974
Abstract A detailed quantitative description of fluid flow in small diameter, porous tubes is of obvious interest to renal physiologists. An attempt to provide such a description is presented here. Under the assumption that fluid loss from a porous tube is a function of pressure gradients across the tubule wall (osmotic effects are not considered ...

A Model in Hydrodynamics

2009
In December 1976, at a conference at Ecole Centrale in Lyon, France, I presented a result in periodic homogenization for a model which I devised, by playing with the equations of hydrodynamics with the idea of understanding something concerning turbulence. After my talk, Jacques-Louis LIONS gave me pedagogical advice, to never put more than one idea in

Fokker-Planck model of hydrodynamics

Physical Review E, 2015
We present a phenomenological description of the hydrodynamics in terms of the Fokker-Planck (FP) equation for one-particle distribution function. Similar to the Boltzmann equation or the Bhatnager-Gross-Krook (BGK) model, this approach is thermodynamically consistent and has the H theorem.
