Show needs to accommodate a wide variety of database regarding furnace specifications comprised of burners, materials processed, wall refractories, etc. It needs to feature user-friendly CAD-like operation which automatically generates input commands such as boundary condition and numerical meshes. Such an intelligent program would substantially reduce the time and cost required for numerical simulation. The program would facilitate the design of innovative furnaces which used to depend on trial-and-error experimental approaches. Furnace designers who have little knowledge of numerical simulation and computer operation would be able to utilize computer simulation to design and optimize furnaces. The requirements above have led to an intelligent program named 'if-Diss' (Industrial Furnace Design Intelligent Support System). Fig.14 shows one of the main screens of if-Diss. It allows interactive processing of furnace design parameters and predicts furnace performances in a short period of time. More than 50 furnaces have been predicted so far. A wider application of the numerical simulation to the development of a variety of industrial furnaces is expected. Conclusion (1) Flow pattern, temperature distribution, and heating curves of slabs have been successfully predicted for a forge furnace and a reheating furnace with the CFD numerical method. (2)The numerical simulation has been applied to optimize the design parameters of the furnaces equipped with the fDI-regenerative burner system. Optimum design has been successfully predicted to improve the heating performance. (3) A computer program named if-Diss (Industrial Furnace Design Intelligent Support System) has been developed which substantially facilitates the development of innovative industrial furnaces.
