Turbulent Flow and Particle Motion in Continuous Slab-Casting Molds
Turbulent flow in the continuous casting process involves transient phenomena and the transport of inclusion particles and plays an important role in the quality of the steel. As shown in Fig. 1, the molten steel jet entering the mold may carry inclusion particles (e.g. alumina) and argon bubbles. Liquid flux can also be entrained from the shear of the liquid flow across the top surface and for...
متن کاملMotion of large bubbles in curved channels
We study the motion of large bubbles in curved channels both semi-analytically using the lubrication approximation and computationally using a finite-volume/fronttracking method. The steady film thickness is governed by the classical Landau– Levich–Derjaguin–Bretherton (LLDB) equation in the low-capillary-number limit but with the boundary conditions modified to account for the channel curvatur...
متن کاملMeasuring Suspended Particle Size with High Accuracy
The average particle size and its distribution are undoubtedly major characteristics of a powder, and the average particle size occurs in all correlations related to the powder behaviour in, e.g., packed, moving or fluidized beds, in pneumatic conveying and in dust filtration. When traditional sieving can no longer be used for smaller particles, instrumental techniques, i.e. particle size analy...

15 صفحه اولA Numerical Study of Drop Motion in Poiseuille Flow
The cross-stream migration of a deformable drop in two-dimensional Poiseuille flow at finite Reynolds numbers is studied numerically. In the limit of a small Reynolds number (<1), the motion of the drop depends strongly on the ratio of the viscosity of the drop fluid to the viscosity of the suspending fluid. For a viscosity ratio 0.125, the drop moves toward the centre of the channe while for t...
