Abstract:
1. A flow plug for minimizing eddy currents, comprising: a plug adapted to be fitted in a conduit and supporting a fluid flow therethrough in a given direction, said plug having an outer radial wall formed with an inner surface wherein a thickness of said outer radial wall is defined, said plug further having an inlet and an outlet with a plurality of open flow channels being formed between said inlet and said outlet, said inlet defining a first plane of incidence for the fluid flow entering said plug, said outlet defining a second plane of incidence for the fluid flow exiting said plug, said plug further including a central region thereof coupled to said inner surface of said outer radial wall and forming at least a portion of each of said open flow channels, each of said open flow channels including (i) a first portion that originates at said inlet and converges to a location within said plug that is downstream of said inlet wherein convergence of said first portion is contributed to by changes in said thickness of said outer radial wall and divergence of said central region, and (ii) a second portion that originates within said plug and diverges to said outlet wherein divergence of said second portion is contributed to by changes in said thickness of said outer radial wall and convergence of said central region, said plug being devoid of planar surface regions (i) at each of said inlet and said outlet, and (ii) in any fluid flow plane thereof that is perpendicular to the given direction, and wherein, for at least a portion of said open flow channels, a central axis passing through said first portion and said second portion is non-parallel with respect to the given direction.
