Mixture Temperature-Controlled (MTC) combustion is a novel concept, offering 50% reduction in NOX emission compared to V-shaped flames without known compromise. The essence of this concept the central cold air injection, which also atomizing medium plain-jet airblast atomizer presently delay fuel–air mixture ignition. Hence, flame root not anchored fuel nozzle or burner lip, facilitating distri...

In spray painting applications, it is essential to generate a spray gun trajectory such that the entire surface is completely covered and receives an acceptably uniform layer of paint deposition; we call this the “uniform coverage” problem. The uniform coverage problem is challenging because the atomizer emits a non-trivial paint distribution, thus making the relationships between the spray gun...

We describe the fabrication of a surface acoustic wave (SAW) atomizer and show its ability to generate monodisperse aerosols and particles for drug delivery applications. In particular, we demonstrate the generation of insulin liquid aerosols for pulmonary delivery and solid protein nanoparticles for transdermal and gastrointestinal delivery routes using 20 MHz SAW devices. Insulin droplets aro...

Piezoelectric atomization, which breaks liquid into tiny droplets, is widely used in aerospace, medicine, and health. Most research piezoelectric atomizers has increased the atomization amount by improving mechanical structure optimizing vibration characteristics. However, as core component of atomizer to realize using dynamic conical angle effect, micro-tapered hole on atomizing sheet not been...

This research presents 3D steady-state simulations of a skim milk spray drying process in counter-current configuration dryer. A two-phase flow involving gas and discrete phase is modeled using the Eulerian–Lagrangian model with two-way coupling between phases. The kinetics incorporated Reaction Engineering Approach. predictions are found to be accordance experimental temperature measurements m...

It’s January, and an aluminum skiff glides slowly across the waters of an old, flooded railroad tunnel in northern Georgia. Its lone passenger is an atomizer, a machine commonly used to disperse air fresheners or mosquito repellents. Over the course of its half-hour journey through the 430-m tunnel, the atomizer sprays an aerosolized cocktail of antifungal compounds that drift up to the craggy ...
