Studies on Merging Characteristics of Isothermal Two Dimensional Identical Triple Jets Using CFD

摘要

Jets have been the topic of extensive research for the past many decades since it has been the basic element in the study of free shear flow. Jets form the basic flow module in many industrial applications especially in Heating Ventilating and Air Conditioning. Multiple jet modules of different shapes and configurations form the basic structure of the air distribution systems. The merging and mixing characteristics of the shear layer and potential core of the individual jets plays a major role in the formation of a combined jet of desired qualities. The combined jet characteristics are a strong function of basic configuration of the jet orifices. The size and the distance between orifices (Pitch) have strong influence on the behavior of the combined jet. The present study focuses on explaining the merging characteristics of identical triple jet (three jets of same diameter) configuration for different diameters and pitch values by modeling and analyzing with the help of CFD tools.
