Summary
Fluid-based manufacturing processes are central to a wide range of industrial applications, including casting, coating, additive manufacturing, chemical processing, cooling, and lubrication. These processes inherently involve complex and tightly coupled interactions among fluid flow, heat and mass transfer, phase change, and material behavior, often spanning multiple spatial and temporal scales.
Despite their technological importance, conventional fluid-based processing systems frequently exhibit limitations in terms of energy efficiency, material utilization, and environmental sustainability. High energy consumption, process-induced waste, and emissions remain critical challenges, particularly in large-scale and high-performance manufacturing environments.
In response, growing attention has been directed toward the development of sustainable and optimized processing strategies. Advances in computational fluid dynamics, multiphysics modeling, and data-driven techniques, including artificial intelligence and machine learning, are enabling more accurate prediction, control, and optimization of complex transport phenomena. These approaches support the design of next-generation manufacturing systems that are both resource-efficient and environmentally responsible.
