Analysis of magnetic field effect on 3D melt flow in CZ Si growth

Computer Modelling of Bulk Crystal Growth

“…An alternative to the RANS approach is large-eddy simulation (LES) [46,63]. Recently, Ivanov et al [64] have proposed a hybridized method in which RANSderived equations are applied in wall regions and LES-derived equations are applied in the core region. Each of these attempts to model turbulent transport has been a mixed success, and no clear choice of turbulence model has emerged.…”

Heat, mass and momentum transport behaviors in directionally solidifying blade-like castings in different electromagnetic fields described using a continuum model

“…(1)- (19) for describing the EM-STP behaviors in a binary solidification process. All these variable fields are coupled one to each others, among which the dominant couplings include the nonlinear and strong correlations of solidification T-f S -C L and P L -V L .…”

“…Some promising or in use EPM applications may include: using transverse or vertical static magnetic field to alleviate or control the natural convections in crystal growth processes [16][17][18][19] or penetration of pouring alloy melts deep into bulk liquid zones (electromagnetic brakes (EMBR)) in continuous casting (or DC casting) processes of various metallic ingots [20][21][22] [22][23][24][25], or grain refining of the solidified ingots through EM stirring/vibrating generations [26,27] etc. Therefore, it is of practical importance to perform modeling for the transport phenomena of heat energy, species mass and momentum of melt flow in various crystallizing materials or solidifying alloy ingots/castings which may be under various EM-fields.…”

Computational Fluid Dynamics Study of Molten Steel Flow Patterns and Particle–Wall Interactions Inside a Slide-Gate Nozzle by a Hybrid Turbulent Model

“…The main idea is to apply an RANS model for near-wall layers, and LES model for the detached zones and regions far away from the wall. [30] This approach resolves the issues associated with LES model in simulating internal flows, and therefore decreases the LES demand of extremely fine mesh elements at wall boundary layers. In this study, the results of DES model have been compared with standard k-e and LES-WALE simulation results.…”
