Numerical Modeling and Simulation of Fluid Flow in Advanced Materials Processing

Recent years have seen a tremendous growth in the development of techniques for materials processing as well as new materials to meet the challenges posed by a wide range of applications, such as those in electronics, telecommunications, aerospace, transportation, energy, environmental control and safety. Some of the advanced materials of particular interest are semiconductor and optical materials, composites, ceramics, biomaterials, advanced polymers, and specialized alloys. This presentation focuses on the fluid flow and associated transport phenomena that arise in many relevant processes and are critical to the quality and characteristics of the final product, as well as to the operation and optimization of the system. Processes such as optical fiber drawing, coating, crystal growth, 3D printing, casting, thin film deposition, and polymer processing are intricately dependent on the flow. This review discusses the main aspects that must be considered in materials processing and the link between the fluid flow phenomena and the resulting product, considering analytical, experimental and numerical approaches that may be employed to study and simulate the flow. The complexities that are inherent in materials processing such as large material property changes, non-Newtonian behavior, free surface flows, complicated domains, combined mechanisms, and complex boundary conditions are discussed. The basic equations that describe the phenomena for typical processes, along with important simplifications and specialized methods, are outlined.
Various important processes and materials are discussed in order to present the appropriate solution strategies and typical results from numerical modeling. The field is obviously a vast one and only a few processes are considered in detail. Among the processes considered here are polymer extrusion, optical fiber drawing and coating, phase-change processes, continuous processing, and chemical vapor deposition for the fabrication of thin films. The effect of fluid flow on the characteristics of the final product are discussed. The results also illustrate the nature of the critical problems in this area and the means to meet the challenges posed. The review also discusses current trends in materials processing and outlines future research needs. Of particular importance are experiments that would provide data for model validation and for better understanding of the underlying fluid flow mechanisms. Also, accurate material property data are strongly needed to obtain accurate results that can form the basis for optimization of the process. Innovative modeling and numerical approaches need further development to study the complex flows that commonly arise in materials processing.
