Summary
Fluid mechanics remains a cornerstone of modern engineering and scientific research, deeply intertwined with advances in aerospace, energy, biomedical systems, industrial processes, and increasingly, materials science. This special issue seeks to highlight cutting-edge developments in mathematical and computational modeling of fluid flows, with a renewed emphasis on how fluid dynamics shapes the behavior, processing, and synthesis of materials across scales.
The issue will feature innovative methodologies—ranging from first-principles modeling and data-driven approaches to hybrid analytical-computational techniques—aimed at understanding and predicting complex fluid phenomena such as turbulence, multiphase flows, and the behavior of nanofluids and hybrid nanofluids in structured and irregular geometries. These flows play a critical role in material processing techniques (e.g., casting, additive manufacturing, and crystal growth), heat and mass transfer in composites, and design of functional fluids with tailored rheological or thermal properties.
A key focus will be the translation of theoretical models into robust tools for engineering and materials applications. This includes systems for thermal regulation, drug delivery, materials synthesis and flow-assisted self-assembly of nano- and microstructures. The issue encourages contributions that reveal the fluid-mechanics-driven dynamics underpinning material design, fabrication, and performance.
Topics of interest include, but are not limited to:
· Differential equations-based models in fluid mechanics with relevance to materials processing and transport phenomena.
· Numerical techniques for nonlinear systems in fluid mechanics as applied to porous media, soft materials, or complex interfaces.
· Nanofluid and hybrid nanofluid models with applications in thermal management, microfluidics, and advanced materials development.
· Fractional order systems capturing memory and anomalous transport effects in complex fluids and soft matter.
· Single and multiphase flow phenomena relevant to solidification, emulsions, and fluid-assisted material shaping.
· Magnetohydrodynamic flows with applications in metallurgy, electrochemical processing, and smart fluid systems.
· Uncertainty quantification and validation of fluid models against experimental data in materials research.
· Case studies demonstrating successful deployment of fluid models in industrial settings, particularly where material behavior is flow-dependent.
By bridging the gap between theoretical fluid mechanics, materials science, and industrial practice, this issue aims to foster interdisciplinary collaboration and accelerate innovation in fluid-mediated material technologies. We invite original research articles, comprehensive reviews, and technical case studies that demonstrate rigorous modeling approaches with direct impact on materials design, processing, and performance.
