Surface nanobubbles are experimentally known to survive for days at hydrophobic surfaces immersed in gas-oversaturated water. This is different from bulk nanobubbles, which are pressed out by the Laplace pressure against any gas oversaturation and dissolve in submilliseconds, as derived by...

Evaporation-triggered microdroplet nucleation and the four life phases of an evaporating Ouzo drop
Download2016-01-01
Tan, Huanshu, Diddens, Christian, Ly, Pengyu, Lohse, Detlef
Evaporating liquid droplets are omnipresent in nature and technology, such as in inkjet printing, coating, deposition of materials, medical diagnostics, agriculture, the food industry, cosmetics, or spills of liquids. Whereas the evaporation of pure liquids, liquids with dispersed particles, or...

Influence of Cold-Wire Tandem Submerged Arc Welding Parameters on Weld Geometry and Microhardness of Microalloyed Pipeline Steels
Download2016-01-01
Mohammadijoo, M., Henein, H., Collins, L., Ivey, D.G.
Tandem submerged arc welding with an additional cold wire (CWTSAW) is being developed for pipeline manufacturing to improve productivity in terms of deposition rate and travel speed of welding. An appropriate understanding of the welding conditions to guarantee requisite weld geometry, appearance...

Demulsifier Performance in Diluted Bitumen De-watering: Effects of Mixing and Demulsifier Dosage
Demulsifier Performance in Diluted Bitumen De-watering: Effects of Mixing and Demulsifier Dosage
Download2016-10-02
Bhattacharya, Sujit, Arora, Nitin, Ng, Samson, Chong, Jeng Y., Kresta, Suzanne M., Machado, Marcio B.
Mixing conditions were explored as a possible avenue for improvement of demulsifier performance in solvent diluted bitumen de-watering process. The effects of demulsifier bulk concentration, demulsifier injection concentration and mixing energy on water and solids removal from the oil phase were...

Estimation of Droplet Size and Temperature at which Solidification starts in a Drop Tube-Impulse System.
Download2016-01-01
Delshad Khatibi, P., Henein, H.
D2 tool steel powders were produced using a drop tube-impulse atomization technique. In order to measure the radiant energy and droplet size of atomized D2 steel droplets, DPV-2000 (Tecnar Automation Ltée, St. Hubert Quebec, Canada) was utilized. In-situ velocity and droplet size of the atomized...

Quantification of Dendritic and Eutectic Nucleation Undercooling in Rapidly Solidified Hypo-Eutectic Al-Cu Droplets
Download2016-01-01
Bogno, A.-A., Delshad Khatibi, P., Henein, H., Gandin, Ch.-A.
This paper reports on the quantification of primary dendritic and eutectic nucleation undercoolings during rapid solidification of impulse atomized hypo-eutectic Al-Cu droplets. The procedure consists in determining the eutectic fraction of each investigated droplet from the fraction of...

Wiskel, J.B., Ma, J., Valloton, J., Ivey, D.G., Henein, H.
Strain aging of microalloyed steel pipe can occur at the relatively low temperatures associated with the pipe coating process and/or during long term storage. A Box-Behnken statistical design is used to determine the significant strain aging variables that affect the longitudinal yield strength...

Characterization of HAZ of API X70 Microalloyed Steel Welded by Cold-wire Tandem Submerged Arc Welding.
Download2016-01-01
Mohammadijoo, M., Kenny, S., Ivey, D.G., Collins, L., Henein, H.
High strength low carbon microalloyed steels may be adversely affected by the high heat input and thermal cycle that they experience during tandem submerged arc welding (TSAW). The heat affected zone (HAZ), particularly the coarse grained heat affected zone (CGHAZ), i.e., the region adjacent to...
