Abstract
This paper uses a newly developed wind tunnel, fitted with grids to generate high levels of turbulence, in order to investigate the effect of velocity fluctuations on the atomization of a liquid jet of acetone. The mean gas velocity at the liquid jet location has been kept roughly constant such that the nominal break-up regime is not affected by an increase in mean shear at the liquid-air interface. Microscopic high-speed imaging is applied to resolve the evolution of the droplets during the atomization process. Results indicate a significant effect of velocity fluctuations on the primary atomization of the liquid jet when increasing the turbulence intensity from approximately 7% to 45%. Further processing of the images will be conducted in the future in order to obtain a more quantitative statistical analysis of this process.
