The influence of impellers system, baffles system and type liquid on gas hold-up in a vessel has been presented this paper. analysis was conducted the basis data obtained vessel. used study inner diameter D = 0.288 m, it filled with up to height H 0.576 m. equipped four planar standard or 24 vertical tubular located circuit. A high-speed consisting two shaft, agitate liquid. six gas–liquid syst...

In the article by Angunawela et al. in the September 2011 issue, the authors used the finite-volume method and advanced computational fluid dynamic modeling to replicate a vitrectomized eye filled with gas tamponade. They computed the relationship between different fractions of gas fill and fluid shear stress on the retina in response to saccadic eye movements and rectilinear head movements and...

Articulated liquid cargo vehicles transporting inflammable fuels and dangerous chemical products require special consideration when traveling on urban roads or cruising at highway speeds. The road safety and handling of these kinds of vehicles may be adversely affected when negotiating sharp turns or travelling on slippery roads, which may result in either lateral instabilities or complete roll...

• A new test rig based on the falling film spray technology was set up. Four different designs such as empty tower, plates were proposed. The heat and moisture recovery performance from flue gas testedsystematically. effects of control parameters water–air ratio inlet air temperature transfer effectiveness examined. Increasing or decreasing can improve for all cases. discharge is rich in water ...

K-theory has its origins in the late 1950s generalization by Grothendieck of the Riemann-Roch theorem [2]. Algebraic geometry utterly baffles me, making me unfit to summarize Grothendieck’s achievement, but he appears to have associated to each X in some family of algebraic spaces a group K(X) that turns out to be a natural repository for information about X and various objects defined “over” X...
