Claim 0:
1. A method of mixing a liquid flowing in a pipe comprising:
securing a nozzle to a wall of the pipe with the nozzle projecting into an interior of the pipe, said nozzle comprising:
a first, outer, cylinder and second, inner, cylinder concentrically arranged about a nozzle axis;
a first duct adapted to receive a first portion of a liquid mass and transporting the first portion of the liquid mass to the interior of the inner cylinder;
a second duct adapted to receive a second portion a second portion of the liquid mass and transporting the second portion of the liquid mass to the interior of the outer cylinder;
the inner cylinder comprising at least one hole arranged to expel liquid therethrough into the interior of the pipe at a first momentum flux ratio; and
the outer cylinder comprising at least one hole arranged to expel liquid therethrough into the interior of the pipe at a second momentum flux ratio;

connecting one of the first and second ducts to a liquid withdrawal scoop downstream of the nozzle;
withdrawing the first and second portions of the liquid mass using the liquid withdrawal scoop;
pumping the withdrawn first and second liquid portions to the interior of the inner and outer cylinders respectively; and
expelling liquid into the interior of the pipe through the holes in the inner and outer cylinders at different momentum flux ratios.
