Mesh Reynolds Number Constraint
Hi Dear Friends,
I would like to know how to determine the constrait on mesh Reynolds number (or Peclet number), for example, by using usual central difference approximations. Thnak you very much. |

Re: Mesh Reynolds Number Constraint
I would refer you to Hirsch's CFD text Volume I. Note that you will have to specify a particular equation before you can get started on this problem.

Re: Mesh Reynolds Number Constraint
Thank You BOb,
I have been thinking in the following one-dimensional equation (Eliptic equation): C*Ux - v*Uxx = 0,where C is constante, and v is the kinematic viscosity of the fluid. By discretizing this equation in a particular point, we obtain one equation involving the coeficients (in 2D or 3D one system). So, the Mesh Reynolds Number Constrait appear when we resolve the discretized equation. |
