In this chapter, the incompressible Navier-Stokes equations in Cartesian co-ordinates discretized on uniform grids will be considered, discussing most of the basic numerical principles in a simple setting. In practical applications, of course, nonuniform grids and general coordinate systems are ...
生活中处处是流体,大到海洋,小到烟雾,流体在计算机图形学中扮演着重要的作用,这本书将介绍这些流体动画的基础仿真。 最著名的公式是incompressible Navier-Stokes equations: 1.1 符号 u→用来表示流体的速度 ρ用来表示流体的密度 p用来表示流体的压强,表示流体在单位面积上施加的力 g→用来表示重力 ν表示流体的粘性...

We discretize the incompressible Navier–Stokes equations on a polytopal mesh by using mimetic reconstruction operators. The resulting method conserves discrete mass, momentum, and kinetic energy in the inviscid limit, and determines the vorticity such that the global vorticity is consistent with the bou...
We are concerned with the existence and uniqueness issue for the inhomogeneous incompressible Navier‐Stokes equations supplemented with H 1 initial velocity and only bounded nonnegative density . In contrast to all the previous works on those topics, we do not require regularity or a positive lower...
Stabilized methods are proposed and analyzed for a linearized form of the incompressible Navier-Stokes equations. The methods are extended and tested for the nonlinear model. The methods combine the good features of stabilized methods already proposed for the Stokes flow and for advective-diffusive flo...
A new pressure formulation for splitting methods is developed that results in high-order time-accurate schemes for the solution of the incompressible Navier-Stokes equations. In particular, improved pressure boundary conditions of high order in time are introduced that minimize the effect of erroneous ...
It is well known that the lattice Boltzmann equation method (LBE) can model the incompressible Navier-Stokes (NS) equations in the limit where density goes... Zou QS.,Chen SY.,Doolen GD.,... - 《Journal of Statistical Physics》 被引量: 0发表: 1995年 Lattice Boltzmann method for two-di...
In this paper, an implicit fractional-step method for numerical solutions of the incompressible Navier–Stokes equations is studied. The time advancement is decomposed into a sequence of two steps, and the first step can be seen as a linear elliptic problem; on the other hand, the second step...
