The design of turbulence amplifiers is given a rational basis by identifying the critical parameter groups necessary to completely specify the performance of a given element, deriving by analysis or experiment the relationships between these nondimensional parameter groups, and developing a rational procedure for obtaining a quantitative dimensioned set of operating characteristics from these relationships. Part I of this paper outlines the problem, identifies the required relations, and presents analyses confirmed by data. These analyses develop relationships for tube pressure-flow characteristics, jet attenuation, and recovered pressure. Part II presents empirical relationships specifying jet stability and control characteristics, and develops a design procedure with an example.
