Zusammenfassung: | •The 3D-LIF method for liquid-liquid system was developed using galvanometer scanner.•The 3D shape of the liquid jet in a shallow pool was reconstructed from multiple cross sectional images.•The 3D visualization of the liquid jet behavior was conducted and the drop behavior around the liquid film was observed.•From the 3D shape data, physical quantities such as droplet diameter and position were calculated.
A new three-dimensional laser-induced fluorescent (3D-LIF) technology to obtain the hydrodynamic behavior of liquid jets in a shallow pool were developed. In this technology, firstly, a refractive index matching was applied to acquire a clear cross-sectional image. Secondly, a series of cross-sectional images was obtained by using a high-speed galvanometer scanner. Finally, to evaluate the unsteady 3D interface shape of liquid jet, a method was developed to reconstruct 3D shapes from the series of cross-sectional images obtained using the 3D-LIF method. The spatial and temporal resolutions of measurement were 0.21 × 0.21 × 1.0 mm/pixel and 2 ms, respectively. The shape of a 3D liquid jet in a liquid pool and its impingement, spreading and atomization behavior were reconstructed using the proposed method, successfully. The behaviors of atomized particles detached from the jet were obtained by applying data processing techniques. Diameters distribution and position of atomized droplets after detachment were estimated from the results. |
