Optimization of structural parameters and numerical simulation of stress field of composite crucible based on the indirect coupling method

Abstract The research starts with the treatment of multiscale transmission problem and establishes electromagnetic solidification coupling mathematical model based on indirect method. It uses three-dimensional magnetic field finite element theory to establish a crucible structure continuous casting built model. This is used optimize parameters composite simulate braking phenomena. results show that L-shaped static has more potent inhibition guidance effect melt circulation. actual downward impact worse. Under influence an field, flow velocity better, state distribution smooth uniform. computational efficiency test conversion calculation time method designed in this study 18.03 min. total 680.48 min, which superior traditional methods. proves can accurately analyze at same ensure superiority its computing efficiency.
