Artificial stomach reveals fluid dynamics of food digestion
stomach food digest hydrodynamics
2021/8/10
Scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how complex flow patterns and mechanical stresses in t...
Fundamentals of Geophysical Fluid Dynamics is a new textbook that provides an introduction to the basic dynamics governing fluid motion in a rotating system. This book is designed for first-year gradu...

2011/8/25
Abstract: In the context of some bidimensionnal Navier-Stokes model, we exhibit a family of exact oscillating solutions $\{u_{\epsilon}\}_{\epsilon}$ defined on some strip $[0,T]\times\R^2$ which does...
Causal Relativistic Fluid Dynamics
Relativisitic fl uid dynamics relativistic kinetic theory expand- ing medium
2011/10/18
We derive causal relativistic fluid dynamical equations from the relaxation model of kinetic theory as in a procedure previously applied in the case of non-relativistic rarefied gases. By treating spa...
The Tibetan singing bowl: acoustics and fluid dynamics
Tibetan singing bowl acoustics fluid dynamics
2011/7/7
We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behavior is rationalized in terms of the related dynamics of standi...
Momentum conservation in dissipationless reduced-fluid dynamics
Momentum conservation dissipationless reduced-fluid dynamics
2010/12/15
The momentum conservation law for general dissipationless reduced-fluid (e.g., gyrofluid) models is derived by Noether method from a variational principle. The reduced-fluid momentum density and the r...
