The effect of water droplets on strained methane-air laminar flames is investigated using particle image velocimetry both gas and liquid phases. We use the impinging flame configuration to measure speed (gas) as well motion phase, simultaneously. Water mean diameter 36.6 µm are produced by an ultrasonic atomizer dispersed in a methane/air flow, for constant molar ratio (12–36%) fuel (methane). ...

in this study a nonlinear asymmetric instability analysis carried out to study primary atomization of annular liquid sheets emanating from the prefilming airblast atomizer using a perturbation method and potential flow assumption. in this direction, firstly governing equations derived according to potential flow assumption and conservation equations while dynamic and static boundary condition a...

Atmospheric pressure plasmas are emerging as an effective means to produce reactive nitrogen species (RNS) in water with potential applications in irrigation with plasma-treated water for enhanced agriculture. Indeed, roles of RNS, mainly nitric oxide (NO), nitrite (NO2 ) and nitrate (NO3 ) in plant biology have been well studied [1]. The acidity and RNS concentration in treated water have been...

INTRODUCTION Topical airway anesthesia is known to improve tolerance and patient satisfaction during flexible bronchoscopy (FB). Lidocaine is commonly used, delivered as an atomized spray. The current study assesses safety and patient satisfaction for nasal anesthesia of a new atomization device during outpatient bronchoscopy in lung transplant recipients. METHODS Using a prospective, non-bli...

This work describes the method of a selective hydride generation-cryotrapping (HG-CT) coupled to an extremely sensitive but simple in-house assembled and designed atomic fluorescence spectrometry (AFS) instrument for determination of toxicologically important As species. Here, an advanced flame-in-gas-shield atomizer (FIGS) was interfaced to HG-CT and its performance was compared to a standard ...

Rotary atomizers are mainly used in agricultural manned aircrafts. Atomization characteristics at high speeds have been studied, but methods to measure the atomization efficiency not elucidated. The of rotary under high-speed airflow was investigated using an IEA-I wind tunnel experimental installation, AU5000 atomizer, and a laser diffraction particle size analyzer. Accordingly, model equation...
