Cylindrical liquid jets are inherently unstable and eventually break into drops due to the Rayleigh-Plateau instability, characterized by the growth of disturbances that are either convective or absolute in nature. Convective instabilities grow in amplitude as they are swept along by the flow, while absolute instabilities are disturbances that grow at a fixed spatial location. Liquid jets are n...

Abstract Submerged and impinging jets with harmonic perturbations added to the inlet velocity profile nozzle vibrations are simulated numerically at different Reynolds (Re) Strouhal (St) numbers by solving Navier–Stokes equations. The effects of Re, St forcing amplitudes on flow behavior jet splitting phenomena studied.

Impinging jets have been used for a wide variety of applications where high rates of heat transfer are desired. This report will present a review of heat transfer correlations that have been published. The correlations were then added to the LEWICE software to evaluate the applicability of these correlations to a piccolo tube anti-icing system. The results of this analysis were then compared qu...

A moving metallic plate subject to heating and cooling boundary conditions is considered in this work. The plate is heated by an imposed heat  ux, and cooled down by an array of impinging jets through convection and radiation. The objective of the present work is determination of operating conditions for controlling the temperature distribution at the end of both heating and cooling sections. ...
