Evaporation of biomass pyrolysis oil as single droplets
… usually introduced into the burner as sprays of droplets; therefore, the evaporation behaviour of individual fuel droplet has an important role in understanding of the combustion characteristics of the droplets in spray combustion and in the burner performance. Single droplet …

Liquid extraction with single droplets-effect of chemical reaction
… a benzene continuous phase into falling water droplets and undergoing a first order irreversible reaction with the water droplets ... The experimental solute transport rates were a factor of 7 to 10 greater than those predicted by the circulating drop model (or Penetration theory) and a factor …

A study of the drying of single droplets in free-flight
The literature relating to evaporation from single droplets of pure liquids and the drying of solution and slurry droplets, and of droplet sprays has been reviewed. The heat and mass transfer rates for individual droplets suspended in free-flight, were investigated using a specially-designed …

Auto-Ignition of Liquid n-Paraffin Fuels Mixtures as Single Droplets Using Continuous Thermodynamics
… a model to predict the auto-ignition time of single droplets of n-paraffin fuel mixtures using the method of continuous thermodynamics. The model uses experimental data for pure fuels to fit rate parameters for a single-step global chemical reaction equation; from this, correlations for rate …

The hydrodynamic behaviour and mass transfer characteristics of single droplets in a pulsed sieve plate column
… behaviour and mass transfer characteristics of droplets in turbulent and non-turbulent conditions have also been reviewed. Hydrodynamic behaviour, i.e. terminal and characteristic velocity of droplets, droplet size and droplet breakup processes, and mass transfer characteristics of single …

A droplet evaporation model for high temperature and pressure spray applications
A zero-dimensional single droplet evaporation model, suitable for the high temperatures and high pressures encountered in diesel engines, has been developed, based on an extensive review of previous work on droplet evaporation. The new model includes the dependence of gas and liquid thermodynamic …

High-throughput multiplexed transcriptome and protein measurements in single cells
… measurements of transcriptome and proteome in single cells. This method takes advantage of droplet barcoding and hydrogel chemistry to capture mRNAs and proteins in thousands of cells. We report the challenges of acquiring sequencing data from cell gels due to complex mechanisms underlying bead …

High precision electrohydrodynamic printing of polymer onto microcantilever sensors
… printing to deposit 2 – 27 um diameter polymer droplets onto microcantilever sensors. The polymer droplets were deposited as single droplets or organized patterns, with sub-μm control over droplet diameter and position. The droplet size could be controlled through a pulse-modulated source …

Mechanisms of drying of skin forming materials
The literature relating to evaporation from single droplets of pure liquids, and to the drying of droplets containing solids and of droplet sprays has been reviewed. The heat and mass transfer rates for a single droplet suspended from a nozzle were studied within a 42mm I.D. horizontal wind tunnel …

Specialized Inter-Particle Interaction Lbm For Patterned Superhydrophobic Surfaces
… strong potentials to qualify for simulating droplets wettability. This is due to its realistic nature of droplet contact angle (CA) prediction on flat smooth surfaces. But SC-LBM was not able to replicate the CA on rough surfaces because it lacks a real representation of the physics at work …

Development of a Metal Droplet Generator for Studying Impact Dynamics
… dynamics and the deposition process of the droplets must be understood and ultimately controlled. In this thesis, I describe the optimization and implementation of an experimental setup for generating droplets of tin and for studying their impact dynamics. In particular, this thesis explains …

On-line laser desorption/ionization mass spectrometry
… was studied using the ball inlet interface and a single droplet generator. Single droplets with 100 picoliter volume were ejected by a piezoelectric actuated droplet generator and deposited onto the ball inlet. Analyte droplets were placed onto a pre deposited matrix layer during on line analysis, …

Black Liquor Droplet Combustion and Modeling
… investigation documents new experimental data on single droplet pyrolysis and combustion in a laboratory furnace that mimics many of the essential features of commercial boilers (temperature, composition, droplet size, etc.). These experiments monitored single droplets placed on a thermocouple …

Comprehensive Black Liquor Droplet Combustion Studies
… equipment, several aspects of which are unique. Single droplets were suspended on a thermocouple and heated in a furnace. Simultaneous diameter (size and shape), internal and surface temperatures, surface emissivity, and mass were measured under various furnace temperatures and gas compositions. …

Model studies of metal-slag reactions in reaction generated foams.
… the oxygen by a hydrogen chloride-nitrogen jet. Droplets of amalgam ejected from the bath by the impinging gas jet, reacted with the hydrogen chloride dissolved in the model slag to produce bubbles, thus forming a dynamic foam. To gain more information about the fundamental refining processes in …
