INTERNAL FLOW PHYSICS OF A FLUIDIC OSCILLATOR SPRAY IN THE TRANSITION REGIME
Tomac, Mehmet N.; Gregory, James W. (BEGELL HOUSE INC50 NORTH ST, DANBURY, CT 06810, 2016)An experimental investigation of the underlying flow physics of a dual-jet interaction fluidic oscillator spray has been conducted in the transition regime for a Reynolds number of 1680. The transition regime is defined ... -
Internal jet interactions in a fluidic oscillator at low flow rate
Tomac, Mehmet N; Gregory, James W. (SPRINGER, 2014)This study focuses on the internal jet interactions and the oscillation mechanism of the feedback-free fluidic oscillator at low flow rate, corresponding to a Reynolds number of 1,350 (based on exit nozzle width and average ... -
Jet interactions in a feedback- free fluidic oscillator at low flow rate
Tomac, Mehmet Nazım; Gregory, James W. (American Institute of Aeronautics and Astronautics Inc., 2013)In this work, the internal fluid dynamics and frequency characteristics of feedback-free fluidic oscillators are investigated experimentally for low flow rates below 3.4 mL/s. The internal flow field of feedback-free fluidic ... -
Oscillation characteristics of mutually impinging dual jets in a mixing chamber
Tomac, Mehmet N.; Gregory, James W. (AMER INST PHYSICS, 1305 WALT WHITMAN RD, STE 300, MELVILLE, NY 11747-4501 USA, 2018)In this study, we consider the oscillatory behavior of mutually impinging jets in an enclosed, domeshaped mixing chamber. The frequency of the impinging jet oscillations is dictated by the flow rate, with the oscillatory ... -
Phase-Synchronized Fluidic Oscillator Pair
Tomac, Mehmet N; Gregory, James W. (AMER INST AERONAUTICS ASTRONAUTICS, 1801 ALEXANDER BELL DRIVE, STE 500, RESTON, VA 22091-4344 USA, 2019)The relative phase of oscillating jets from a pair of fluidic oscillators was synchronized in this work. The means for this synchronization was mutual interaction through a shared feedback channel between the two oscillators. ... -
A review of fluidic oscillator development and application for flow control
Gregory, James W.; Tomac, Mehmet Nazım (2013)This review provides a detailed discussion of the historical development of fluidic oscillators and their application to flow control. Fluidic oscillators were initially developed in the 1960's for a variety of applications, ...
