| Abstract: | Aim to explore the computation standards for finite element analysis of thermal analysis of the fluid fields of the front-box and the nozzle-shaped space of aluminum roll-casting; The computation was performed by using coupled fluid-thermal FEM simulation of the FLOTRAN module of the general finite element analysis software, ANSYS. Postprocessing by Ansys and stricter analysis of results by software MATLAB was reviewed. The allowable inhomogeneity and its applicabilities of temperature of outlet for thermal field finite element analysis were rendered down from observations and recorded data of two industry experiments in reality.5figs.,1tab.,11refs. |
