The natural flow and the critical exponent

, 2023
Inspired by work of Besson-Courtois-Gallot, we construct a flow called the natural flow on a nonpositively curved Riemannian manifold $M$. As with the natural map, the $k$-Jacobian of the natural flow is directly related to the critical exponent $δ$ of the fundamental group.

Lab-on-PCB and Flow Driving: A Critical Review

Micromachines, 2021
Lab-on-PCB devices have been developed for many biomedical and biochemical applications. However, much work has to be done towards commercial applications. Even so, the research on devices of this kind is rapidly increasing.

Enhanced dissipation for the 2D couette flow in critical space [PDF]

Communications in Partial Differential Equations, 2019
We consider the 2 D incompressible Navier-Stokes equations on with initial vorticity that is δ close in to −1(the vorticity of the Couette flow ). We prove that if where ν denotes the viscosity, then the solution of the Navier-Stokes equation approaches ...

Critical properties of spherically symmetric black hole accretion in Schwarzschild geometry [PDF]

, 2007
The stationary spherically symmetric accretion flow in the Schwarzschild metric has been set up as an autonomous first-order dynamical system, and it has been studied completely analytically.

Characteristic Analysis and Model Validation of Supercritical Carbon Dioxide Ejection in Pressure Vessel

Yuanzineng kexue jishu, 2023
When the pressure vessel of supercritical carbon dioxide energy conversion system breaks, very complex ejection phenomena will occur, and its critical flow characteristics need to be studied urgently.

A spinorial energy functional: critical points and gradient flow [PDF]

, 2015
On the universal bundle of unit spinors we study a natural energy functional whose critical points, if dim M \geq 3, are precisely the pairs (g, {\phi}) consisting of a Ricci-flat Riemannian metric g together with a parallel g-spinor {\phi}.

The role of flow geometry in influencing the stability criteria for low angular momentum axisymmetric black hole accretion

, 2010
Using mathematical formalism borrowed from dynamical systems theory, a complete analytical investigation of the critical behaviour of the stationary flow configuration for the low angular momentum axisymmetric black hole accretion provides valuable ...
