摘      要：The current work combines numerical and experimental investigations based on a small-scale mockup using the eutectic alloy *** jet flow discharging from the submerged entry nozzle was exposed perpendicularly to a DC magnetic field across the entire wide face of the *** calculations were performed by using the commercial package CFX with an implemented RANS-SST turbulence *** anisotropic properties of the MHD turbulence were taken into account by specific modifications of the turbulence *** comparison between our numerical calculations and the experimental results shows a very well *** particular,the modified RANS-SST turbulence model is capable to reconstruct the peculiar phenomenon of the excitation of non-steady,non-isotropic large-scale flow perturbations caused by the application of the DC magnetic *** important finding of our study is the feature that the electrical boundary conditions,namely the wall conductivity ratio,have a great impact on the mold flow subjected to an external magnetic field.
