Visualization of multijet impingement flow

Abstract

F visualization experiments were conducted in water as the working medium to study multijet impingement flows with fountain formation. The visualization technique uses fluorescein-sodium, a fluorescent dye, as tracer fluid and illumination by a sheet of light obtained by spreading a laser beam. Streakline photographs were also taken using air bubbles as tracer particles. Stagnation-line patterns were recorded for the cases of two-, three-, and four-jet configurations and compared with theoretical predictions.
