Current Status of Three Dimensional Growth Laws

چکیده
We review current theory, simulation and experiment for the growth of 3D bubbles in ideal dry froth. Theories assume either that the growth rate depends on bubble radius or topology. Radius based laws violate the Young-Laplace law. Topological theories can be either linear or non-linear in the number of faces (f). The growth law can hold either exactly for each bubble (as in 2D) or apply only to ensembles of bubbles with a given topology. Recent experiments suggest that the growth law is linear in f, but holds only for ensembles. We still lack both experimental and simulation results for possible growth laws depending on detailed topology or vertex number. Higher accuracy and better statistics are essential to resolve these issues.

In this paper, the spreading of three-dimensional, turbulent and unsteady inclined turbidity currents has been investigated. The experimental results were normalized in the form of non-dimensional plots and then a theoretical model was developed. The current width, b, and the relative situation of the tip of the nose of turbidity current, x, are normalized with respect to the buoyancy length sc...

For a Czochralski growth of Ge crystal, thermal fields have been analysed numerically using the three-dimensional finite volume method (FLUENT package). The arrangement used in a real Czochralski crystal growth lab included a graphite crucible, heat shield, heating device, thermal insulation and chamber including two gas outlets. We have considered two cases for calculations, which are configur...
