Hello Everyone,
can anyone help me how to create a 3D thin wire screen (see attached picture) ? I want to make stacked multiple wire screens. Fluid will flow through the open space and in the end i am going to study temperature profiles on the wire screen due to the heat transfer from the fluid. Any help, how to draw this kind of screen (see attached picture) in gambit or any other CAD softwares?Plain-Wire-Mesh-Screen.jpg
Thanks..
MM

What are the dimensions of the temperature profile are you going to study? Are they of the same order of the wire screen mesh, or of the whole screen?

Its stack, thus as fluid moves from one end to the other..temp will drop..so temp profile is gonna be different in all direction of the screen.

The porous media model may be used to simulate the wire screen stack. But properties of the stack are needed, usually they can be acquired from experiment.

screen size is not that much fine..its big say 200 openings per cm^2..

That very fine a screen. As a numerical simulation method, CFD model need to use a mesh with a adequate resolution, the minimum requirement is that 5 cells for the worst across any flow passage, 10 is preferable, in rather that the passage in the stack is very complex. In a word, to simulate the flow in a stack of wire screen directly is a challenging task for any CFD system.

Just as that of bulk flow fluid zone. But you may have to replan your research mission.
