This work presents a model where the Navier-Stokes equation is coupled to the advection-diffusion equation. The decomposition method is applied to the two-dimensional non-stationary Navier-Stokes equation and Duhamel's Principle is used to obtain a series approximation of the solution. The ...
为什么纳维-斯托克斯方程(Navier-Stokes equation)只适用于不可压缩实际流体?不适用于可压缩方程吗? 方程里面也有密度符号。若为理想流体,则方程就化为欧拉运动方程式。但欧拉运动方程式是可压缩不可压缩的流体都适用的。 但为什么 N…NS 和 Euler 均有可压缩和不可压缩的形式。牛顿流体粘性切应力与应变成线性...

applications when modeling turbulent flows. Another technique for solving numerically the Navier–Stokes equation is the Large-eddy simulation (LES). This approach is computationally more expensive than the RANS method (in time and computer memory), but produces better results since the larger turbulent...

The motion of anon-turbulent,Newtonianfluid is governed by the Navier-Stokes equation: The above equation can also be used to model turbulent flow, where the fluid parameters are interpreted as time-averaged values. The time-derivative of the fluid velocity in the Navier-Stokes equation is thema...
On the other hand, regarding to Comsol 3.5, I send you a file that test the transmission through a layer of "air" modelled by using a elastic subdomain whose parameters (Young modulus and Poisson ratio) are defined in such a manner that the elasticity equation becomes Navier-Stokes. Note ...
