A numerical study of non-circular laminar jets in a secondary stream
Abstract
The effects of the shape of the nozzle on the behavior of a laminar jet in a secondary stream is investigated. The parabolic form of the governing equations written in dimensionless form are presented, and the coordinate system is described. The equations are solved using a forward marching, explicit, finite difference method. The secondary stream velocity ratio, variations in center-line velocity, and half-width variations for cruciform, rectangular, and H-type nozzles with varying arm width-to-nozzle height ratios are calculated. The influence of the perimeter-to-cross-sectional area of the nozzle on the rate of jet mixing is studied.
