Three-dimensional effect of high frequency vibration on convection in silicon melt

Faiza Mokhtari, Slim Kaddeche, Daniel Henry, Samia Bouarab, Abdessamed Medelfef & Valéry Botton

The effect of HF vibrations with different orientations on the convective flow in a liquid metal inside a cubic cell heated from the side is investigated using collocation spectral method. The vibration direction is 3D with a vibration vector contained in one of the three principal planes of the cavity ($xz$-, $xy$- and $yz$-planes). In either weightlessness or gravity conditions, the influence of the vibrations on the flow is found to strongly depend on their direction : each vibration orientation has its own features and affects the flow intensity and pattern differently.
