A 12-month program with the objective to develop a mathematical model of fluid flow in Coanda eductors is about 50 complete. The model is to serve as a tool in design of Coanda eductors for pneumatic conveying of excavated rock materials. Based on work completed, it has been concluded that Coanda eductors possess potential advantages compared to alternate ejectors or other momentum transfer devices. The advantages are primarily related to the simplicity of the mechanical design.
