Description

In the present work, an analysis of geometric parameters of tip nozzles in operation was developed and extrapolations for futures situations were proposed. The main trigonometric relationships to evaluate the possibility of jet coalescence were determined. The results showed that the Primary Circle Diameter (PCD) is not affected only by the geometry of the nozzle, tips with up to 04 (four) nozzles and small angle with the vertical can promote coalescence and tips with more nozzles than four reduce this possibility. This work also presents a relationship between number of nozzles and angle between two adjacent nozzles. An important tool to determining conditions for development of new tips lance is proposed.
