2D laminar fluid simulation with leak

kristaps okorie · July 30, 2015, 08:26

hi guys
i am simulating a 2D laminar in a pipe with leak, but encounter problem with the boundary condition for the leak.wish to know how to go about it. thanks for responding in advance

thanks for responding, but still want to ask if the mesh sizing of leak would be the same as the main outlet?

thanks it was really helpful, but my leak is some where in the middle of the pipe length, and don't really know if its right to have 2 different wall (wall 1 and wall2 ) for the boundary of the wall before the leak and after the leak? thanks

mesh.pdf this the mesh . the more dense area is the leak .thanks

geo.pdf this is also the geometry the pipe.thanks
