ABSTRACT:
An eductor-spike nozzle device includes (a) a first cylindrical member having a first wall including a cowl lip and defining a first hollow interior, and (b) a second cylindrical member mounted within the first hollow interior and having a second wall (i) externally defining an annular flow path with the first wall for flow of a first stream of fluid, and fluid compressing throat region with the cowl lip for creating a high velocity stream, and (ii) internally defining a second hollow interior for flow of a second stream of fluid so as to form the composite stream of high velocity fluid with the first stream of fluid, thereby increasing a probability of the composite stream receiving and entraining particles introduced into the composite stream.
