Preliminary Studies on Compressible Jet Flow from a Pipe with Square Cross-section

Abstract

Jet flow through pipes/nozzles has been successfully applied in various fields and has a further wide scope in fields of Flow Control and Acoustic Suppression. In the past few decades, jet flow through pipes and nozzles have been widely exploited, researchers found that non-Circular Pipes possess some unique properties, with which the need for research in this field increased. This work presents the properties of jet flow from a Square Pipe (L/D=5) over the Circular ones. Experiments are done in Compressible flow conditions using 3-D fabricated Pipes of Circular and Square cross sections. The cross sectional area of the pipe exit is maintained same for both the Pipes to facilitate comparison of results. This study highlights the advantages of Square Pipes over the conventional ones via pressure measurements.
