The use of Coanda effect in energy-efficient recirculating aspiration systems

Abstract

The article suggests an effective way for reduction of energy consumption of the aspiration systems by means of recirculating system with the use of Coanda effect. Operation of the system is organized with partial supplying of removed air from the aspiration hood to the reloading chute via the entry enabling to use Coanda effect. Thus, the supplied air moves in the direction opposite to ejection one and produces aerodynamic resistance reducing its volume that results in considerable reduction of the system’s energy consumption. The article presents the results of the research enabling to evaluate the efficiency of the suggested engineering solution and the data necessary for its design.
