TRANSPORT FROM CONTINUOUSLY MOVING MATERIALS UNDERGOING THERMAL PROCESSING
This chapter presents a detailed consideration of the transport processes associated with a continuously moving material undergoing thermal processing. This problem is of interest in processes such as extrusion, fiber drawing, hot rolling, and continuous casting. Three main approaches are outlined. The first is directed at the heat transfer in the material, assuming convective coefficients at the surface. The second solves for the flow generated by an isothermal or uniform-heat-flux moving surface, focusing on the fluid flow and not on the transport in the material. The third approach is a combination of the first two and considers the conjugate problem that couples the flow and transport in the fluid with those in the material. Therefore, this is the most realistic formulation with respect to practical materials processing systems. The flow may be treated as a boundary layer, or the full, elliptic equations may be solved. Both formulations are discussed, along with the relevant numerical procedures.
