This paper presents an experimental study devoted to the understanding of break-up mechanisms of liquid sheets. A shear instability develops at the interface liquid/gas resulting in an undulated motion of the liquid sheet. These undulations trig a Rayleigh-Taylor instability leading to azimuthal thickness modulations. A model including the development of both instabilities allows us to predict ...

Electrospraying also known as an electrohydrodynamic atomization is a technique for atomizing liquids. The origin of electrospraying is on the base of the charged droplets theory which the interface of the droplets could be deformed by the applied electric field on a liquid droplet which egressing a capillary [1]. Electrospray is a well-known phenomenon which has different applications such as ...

Processes utilizing various spraying cooling are widely used in many gas treatment applications. Effective spray cooling system design optimization often depends on the approach used to investigate such gas cooling problems. The mass transfer efficiency of spray cooling problems depends on the ability of the liquid to atomize and disperse into the gas by interacting in a controlled manner. Expe...

In addition to topical delivery, nasal sprays offer an alternative drug administration route the systemic circulation, therefore avoiding need for painful, invasive delivery techniques. Studies on efficacy of date have been conflicting despite its potential. particular computational studies, e.g. Computational Fluid Dynamics (CFD), spray deposition require realistic initial conditions, which ar...
