Atomization of impinging opposed water jets interacting with an air jet

experimental investigation of atomization of water jets in air streams

atomization is a process by which a volume of liquid is converted spray. this process includes the breakup of the liquid jet or the liquid sheet exiting the injector. this paper has experimentally investigated the models and mechanisms for the breakup of the liquid jet and the liquid sheet formed by the jets impingement in a still environment and in an environment with counter flow, coflow, and...

Numerical Simulation of Primary Atomization of Non-Newtonian Impinging Jets

Newtonian impinging jets have been investigated for decades. However, limited is known about non-Newtonian impinging jets. The present work attempts to improve this situation by performing high-fidelity numerical simulations of non-Newtonian impinging jet dynamics. Emphasis is placed on the near field of the liquid sheet formed by the impingement of two shear-thinning (viscosity deceases with i...

High-Fidelity Simulations of Primary Breakup and Impinging Jet Atomization

Ceramic panel heating under impinging methane-air premixed flame jets

Due to the ever wider use of composite materials within aerospace applications, fireproof tests get recently an increased attention. Numerical simulation is expected in the coming years to accompany engineers in their design work to increase the chance of success in the fireproof certification tests. The current research focuses on the numerical investigation of a premixed methane-air flame imp...

Aerosol Atomization from Transonic Air Jets in Cross Flow

We investigate the droplet size distributions and concentrations produced by an aerosol generator driven by a high velocity air jet delivered in cross flow to an oil tube at Mach numbers of 0.1-1.0, and Weber numbers based on the air flow parameters between 1000 to 40000. Measured Sauter mean droplet diameters (SMD) from 1μm to 3.5μm were determined by an Electronic Low Pressure Impactor over t...
