Flow Characteristics of a Multiple Nozzle Exhaust Gas Eductor System.

Abstract

Cold flow tests of a four nozzle eductor system were conducted to evaluate the flow characteristics of several mixing stack configurations. A previously tested mixing stack design used a plug to shield the primary flow nozzles from view. Flow visualization was used to determine the flow pattern in the stack. The results of the visualization runs were then used to modify the mixing stack geometry. The eductor system flow characteristics were evaluated in terms of non-dimensional parameters governing the flow phenomena from a one dimensional analysis of a simple eductor system. The eductor system's pumping capacity was improved over that of the previously tested unmodified mixing stack. (Author)
