A detailed understanding of the driving mechanisms behind primary atomization is crucial to the optimization of sprays for efficient combustion in modern propulsion systems. Many challenges are associated with simulating realistic turbulent atomization, such as the multiplicity of length and time scales of the turbulent flow field and gas-liquid interface, discontinuous fluid properties and pre...

PURPOSE The purpose of this study was to compare the safety, efficacy and recovery time of intranasal midazolam spray administered using an atomizer to orally administered chloral hydrate and promethazine for the sedation of pediatric dental patients. METHODS A randomized double-blind crossover study design was utilized in which 31 patients (mean age 41.8 months, range 26-58 months) underwent...

The article presents the theoretical background, in particular, developed mathematical models describing technological processes of air-jet formation and influence wind wheel on changes axial velocities air jet, as well range jet by a fan installation with pneumatic disk sprayer. Theoretical studies show that smooth variation velocity flow installations prevent transfer isothermal circular cros...
