Abstract: Rapid progress in the influencing technologies over the past two decades has brought CFD to the forefront of process engineering. Advances in computational technology, a sustained effort by CFD providers to implement comprehensive physical models, and advances in numerical methods have combined to make it possible for engineering and R&D groups to use CFD routinely in many process industry companies. Heat transfer is extremely important in a wide range of materials processing techniques. The transport in closed domains strongly influences the quality of the final product.
Research in thermal materials processing is largely directed at the basic processes and underlying mechanisms, physical understanding, effects of different transport mechanisms and physical parameters, general behavior and characteristics, and the thermal process undergone by the material. It is usually a long-term effort, which leads to a better quantitative understanding of the process under consideration.
This paper provides an overview of how CFD technology is currently being used in the heat transfer approach of muffle furnaces. The overview is achieved by taking into consideration of five influencing factors:effect of CFD technology, model building, mesh generation, relevant physical models and validation.
Incompressible forced convection heat transfer problems normally admit an extremely important simplification: the fluid flow problem can be solved without reference to the temperature distribution in the fluid. Thus, it can first find the velocity distribution and then put it in the energy equation as known information and solve for the temperature distribution.
Also, in this paper it is intended to expand the theoretic researches concerning heat processes intensification and their use in industrial practice.
This paper focuses on the link between basic research on the underlying transport mechanisms and the engineering aspects associated with the process. The results are focused on the heat transfer processes that occur in industrial heating equipments.
