ABSTRACT:
A method of conditioning a flow of fluid comprises the steps of introducing a fluid into a nozzle body having an opening defining an inlet, an opening defining an outlet, and an inner surface connecting the inlet and the outlet, directing the fluid introduced into the inlet of nozzle body over the inner surface, and applying a pressure to the fluid. The inner surface of the nozzle is asymmetric with respect to a centerline of the inlet to provide a first region outside the nozzle of relative maximum pressure and a second region outside the nozzle of relative minimum pressure, where the first and second regions are substantially the same distance from the outlet. A fluid-conditioning nozzle comprises an inlet having an edge defining a first circumference, an outlet, offset from and spaced apart from the inlet, having an edge defining a second circumference, smaller than the first circumference, and a transition surface extending between the inlet and the outlet. The transition surface has a continuously changing slope between the first and second circumferences. The nozzle is operable to provide a first region outside the nozzle of relative maximum pressure and a second region outside the nozzle of relative minimum pressure, where the first and second regions are substantially the same distance from the outlet.
