Abstract
A downhole tool includes an outer sub and a mandrel positioned within the outer sub. The outer sub and the mandrel are tubular. The interior of the mandrel defines a bore flow path, and the annular space between the outer sub and the mandrel defines an annular flow path. One or more nozzle ports are formed in the mandrel to fluidly couple the bore flow path and the annular flow path. A nozzle is positioned in each nozzle port. The nozzle includes a nozzle body having a flow path formed therein to fluidly couple the bore flow path to the annular flow path through the nozzle.
