Moreover, regions of massive separation are usually present with the possibility of flow unsteadiness and turbulence. The chapter reviews the numerical aspects of the discrete solutions of reynolds-averaged Navier鈥揝tokes equations. The various performances of the techniques considered are discussed. ...
改变世界的方程之纳维尔－斯托克斯方程，堪称最难的物理学方程 粘度为μ，密度为ρ的不可压缩牛顿流体，受静水压力p和加速度g的作用，其运动可以描述为满足纳维尔（叶）－斯托克斯（Navier-Stokes）方程的速度矢量场V：我们用复数形式来表示这一个方程，因为它以向量的形式表示了三个方程这些方程式是以克劳德-路易·纳...
The vorticity-stream function formulation of the two-dimensional incompressible Navier-Stokes equations is used to study the effectiveness of the coupled strongly implicit multigrid (CSI-MG) method in the determination of high-Re fine-mesh flow solutions. The driven flow in a square cavity is used...
So I would like to know Comsol 3.5a uses which 'turbulence model' for the 'Incompressible Navier Stokes' module.I couldn't find any information regarding turbulent flow modeling for Incompressible Navier Stokes in the comsol manual Thanks in advance SM Ananth ...

众所周知, 三维不可压缩 Navier-Stokes 系统存在整体 Leray-Hopf 弱解. 当弱解满足 Prodi-Serrin 条件时, 解是正则的. 本文在解正则性条件的判别方面取得了一些新结果. 特别对于轴对称系统, 当旋 转速度为零时, 系统的整体适定性结论是众所周知的. 本文在研究中发现了一个新的守恒量, 进而得 到了旋转速度...
(i) translation or rotation is absent; (ii) both velocities are parallel to the same constant vector. This paper shows the existence of a unique time-periodic Navier–Stokes flow in the small with values in the weak-space and then deduces the desired pointwise decay of the solution under ...
Hi guys, I have a problem when a use the incompressible Navier Stokes with the activation of Flow in porous media (Brinkman Equation). I get the next error: Error: Failed to find consistent initial values. Matrix_has_zero_on_diagonal ...
Equation of incompressible flow For incompressible flow in which the density is assumed to be constant, Navier-Stokes equation can be simplified. Based on the discussions of “Newton’s law of viscosity” in Section 3.2.2.1, the viscosity terms in Navier-Stokes equation can be expressed as: (...
