aXin proved that any smooth solution to the multidimensional Navier–Stokes equations for polytropic fluids in the absence of heat conduction will blow-up in a finite time interval if the initial density is compactly supported 辛证明,对多维的所有光滑的解答在没有热量传导时在有限间隔时间Navier升火等...
how to solve Navier stokes in comsol 4.4Login
Briefly, i'm designing a hydrogen storage tank, which has porous metal hydride bed inside. For the momentum conservation at the porous area, I need to use the given equation below. It seems that physics interface of "Brinkman Equation" gives a similar form of Navier-stokes equation. However,...

All Answers (20) Dear Haftamu, Prediction of weather is connected with solvingpartial differential equations(Navier -Stokes equations). If you need to study this subject you should be good at solving numerically PDE (or ODE in simple model)....
In fluid mechanics, pressure represents the force per unit area applied to a surface by a fluid. Using COMSOL Multiphysics, we can solve the governing equations for fluid flow, theNavier-Stokes equations, to determine the velocity and pressure fields that describe the flow. ...
Here, Fluidity is used to solve the non-hydrostatic incompressible Navier–Stokes equations under the Boussinesq approximation in a rotating reference frame:(1a)∂u∂t+u·∇u+2Ω×u=-∇pρ+∇·ν∇u-gk,(1b)∇·u=0,where u is the 3D velocity vector, t represents time, p ...
When assuming laminar flow, the pressure gradient inside the gas film can be calculated by solving the Navier-Stokes equations, which are rather complicated to solve analytically. How 假设气体分子的无意味道路影片的厚度,影片可以对待连续流小于。 当假设的层流,压力梯度在气体影片里面可以通过解决计算时...
These models include any case where nonlinear terms arise in the governing equations, such as within the Navier–Stokes equations, or whenever materials properties, loads, or boundary conditions are functions of the solution. The solution to such cases is found by repeatedly solving a linearized pro...
