Abstract

An apparatus for fluid flow communication is disclosed which comprises a substantially tubular member having first and second opposite end portions; a first end wall secured to and closing the first end portion of said substantially tubular member wherein the first end wall has at least one first aperture extending therethrough; a second end wall secured to and closing the second end portion of the substantially tubular member wherein the second end wall has at least one second aperture extending therethrough; an intermediate wall disposed within the substantially tubular member intermediate the first and second end walls and having a circumferential outer edge; and support means disposed within the substantially tubular member for fixedly securing the intermediate wall relative to the inner surface of the substantially tubular member whereby the circumferential outer edge of the intermediate wall and the inner surface of the substantially tubular member define a substantially annular passage. A process for mixing a drilling fluid comprises passing components of the drilling fluid through the apparatus.
