Transition in Pipe Size
Transition in Pipe Size
(OP)
I am in the process of developing a mixing stage for a process I am working on. To minimize the overall length in the process flow direction, I have chosen to use mixing elements that are smaller in diameter than the upstream/downstream piping. I am trying to determine a way to minimize the effect of the flow stream reduction/expansion with the use of baffles (I really want, again, to minimize the overall length required for this unit operation). Has anyone ever seen any information related to the sizing/placement/design of baffles to help in distributing the flow at the stepped inlet and outlet of the mixing stage (6" to 3" to 6")? I cannot afford the length required by a "perfect" reducer geometry on both ends of the mixing stage.

RE: Transition in Pipe Size
The mixers do their own job of crerating turbulence (actually, they create shear to be technical about it). I have upstream and downstream processes that rely on the fact that the flowstream occupy the better portion of the 6" tube. Without some form of transition, I would expect the flow on the up/down stream sides to tend towards channeling down the middle, approximating the 3" mixer diameter. Thank you for your reply.
