Abstract
A static fluid mixer includes a cylindrical flow conduit and at least two inclined, axially spaced, and circumferentially offset internal baffle members for creating counter-rotating vortices in fluids passing through the conduit. The baffle members each have upstream edges spaced from an inner surface of the conduit by a first distance less than a radius of the conduit and downstream edges that are spaced from the inner surface of conduit by a second distance that is greater than the first distance. The baffle members can each have a trapezoidal shape with the downstream edge being smaller in length than the upstream edge thereof.
