To explore fluid-thermal analysis of the flow fields of front-box and One-spacer nozzle of aluminum roll-casting, a three-dimensional finite element simulation model has been developed to provide analyzing distribution of velocity and temperature of outlet of nozzle, by using coupled fluid-thermal FEM simulation of FLOTRAN module in ANSYS 6.0.
Accounting of both the nozzle and front-box fields will yield more accurate simulation results.
Based on industrial experiments and simulation, one-spacer nozzle has potential capacities to be designed for higher speed and thinner sheet of roll cast.

The corresponding CFD model was then established on the basis of the experiment study.
When the solid slag layer was not considered, simulation results showed that the parameters such as molten slag flow, rotary speed, disk radius, fluid viscosity and fluid density had important influence on the liquid film thickness at the edge of the disk, but the surface tension of molten slag had little impact [5].
Moreover, they also obtained the film thickness at the edge of rotary disk by numerical simulation.
It was found that the simulation results can predict the experimental data properly.

In an interactive simulation environment, a full multi-phase casting process simulation (thermal-fluid simulation using multi-physical domain) along with its material and mechanical simulations are carried out in a single environment.
In the last couple of decades, the issue of multi-physical coupled simulation technology for cast through process simulation has been a focus of many scientific research works, where a number of advanced simulation methods have been developed.
Thermal Fluid and Mechanical simulation A popular method of casting simulation is an Eulerian fluid-thermal simulation where the whole process of mold filling (fluid zone), solidification (mushy zone) and solid state are modelled using an Eulerian domain.
