Probabilistic estimates for the Two Dimensional Stochastic Navier-Stokes Equations

, 1999
We consider the Navier-Stokes equation on a two dimensional torus with a random force, white noise in time and analytic in space, for arbitrary Reynolds number $R$.

Nonlinear parallel momentum transport in strong turbulence

, 2015
Most existing theoretical studies of momentum transport focus on calculating the Reynolds stress based on quasilinear theory, without considering the \emph{nonlinear} momentum flux-$$.

Periodic Moving Track Analysis of Spiral Oil Wedge Journal Bearing under Dynamic Loading

Journal of Applied Fluid Mechanics, 2018
The moving track of journal bearing changes with the time in the condition of dynamic loading. The force balance equation of journal bearing is established, and the generalized Reynolds equation, the oil film thickness equation of spiral oil wedge ...

Computational analysis of shock-induced flow through stationary particle clouds

, 2019
We investigate the shock-induced flow through random particle arrays using particle-resolved Large Eddy Simulations for different incident shock wave Mach numbers, particle volume fractions and particle sizes.

Elastohydrodynamic lubrication calculations used as a tool to study scuffing [PDF]

A new Reynolds equation was developed that takes into account the nonlinear viscous behavior of the fluid. The new Reynolds equation considers the nonlinear viscous fluid model of Eyring, the equilibrium equation, the constant mass flow, and the ...
