Measurement of the Sea Spray Droplet Size Distributions at High Winds
This project will develop cloud droplet probes and phase-Doppler anemometry for measuring sizesegregated droplet concentrations at high wind speeds in the ABL. The data will be used for investigating droplet dynamics in the marine atmospheric boundary layer, characterizing the droplet surface flux source function, and determining the effect spray drops have on air-water surface exchange process...
متن کاملComprehensive Fuel Spray Modeling and Impacts on Chamber Acoustics in Combustion Dynamics Simulations
The current study focuses on comprehensive fuel spray modeling and its effects on chamber acoustics in combustion dynamics simulations. The fuel spray is modeled using an Eulerian-Lagrangian approach describing the atomizer internal flow, primary atomization, and secondary atomization processes. To anchor the fuel spray model, a series of experiments has been conducted on the fuel atomizer with...
متن کاملSpraying mode effect on droplet formation and ion chemistry in electrosprays.
Depending on the spraying conditions and fluid properties, a variety of electrospray regimes exists. Here we explore the changes in ion production that accompany the transitions among the three axial spraying modes, the burst mode, the pulsating Taylor cone mode, and the cone-jet mode. Spray current oscillation and phase Doppler anemometry measurements, fast imaging of the electrified meniscus,...

Recently, there have been problems with particulate matter pollution in diesel engines and it has reduced production rate of these engines and also, it has accelerated the development of new technologies for PFI and GDI gasoline engines. The spray characteristics has significant impact on the combustion efficiency, power and emissions on internal combustion engines. In This study, effect of inj...
متن کاملAir Assisted Atomization in Spiral Type Nozzles
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...
