Spray generation
This is an experimental investigation of the ligaments and drops generated at the free surface of liquid wall jets and liquid axisymmetric jets flowing over sand and polystyrene (beads) roughed surfaces. Experiments were conducted with freshwater and Eulerian and Lagrangian methods of description …

Investigation into continuous spray and metered spray using compressed gas propellant
… aerosol products are generally based on either spraying continuously (i.e. airfreshners, body spray, hairspray, insecticide, polish and disinfectant) or on spraying on metered liquid dosage. This investigation has focused on two different aerosol products: (i) Continuous spraying aerosol with …

The morphology of spray-dried particles
Samples of Various industrial or pilot plant spray-dried materials were obtained from manufacturers together with details of drying conditions and feed concentrations. The samples were subjected to qualitative and semi-quantitative examination to identify structural and morphological features. The …

Droplet Drag Modeling on Spray Conditions
… of large droplets. In applications such as spray combustion, droplets of various sizes are generated and move with the flow. Large droplets tend to deform in the flow, and they have complex interactions with the flow because of this deformation. To better model spray, the physical …

Structure and stabilization of cryogenic spray flames
… is a realistic model of the base of a cyrogenic spray flame. Through this progression the non-dimensional parameters governing behaviour are introduced successively and the most influential parameters are identified. The final result will aid design both of the engine and the control sequences of …

Agricultural spray droplet dispersion in turbulent windflow
Off-target contamination (or spray drift) during agricultural chemical application, arising from removal of small (diameter < 100 m) droplets from sprays by atmospheric or vehicle-generated cross flows, is investigated experimentally. The primary requirement for realistic wind tunnel studies is …

Porous Materials Prepared by Ultrasonic Spray Pyrolysis
The second approach was used to prepare meso- and macroporous carbons. A variety of carbon morphologies were observed (as indicated by SEM and TEM). Analysis of the carbon precursors using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) suggests that the decomposition …
