Summary

Over the past decades, significant progress has been made in understanding the complex behavior of turbulence in both single-phase and multiphase flows. These advances span a broad spectrum of approaches, including analytical formulations, numerical simulations, and experimental investigations. Such studies are pivotal not only for deepening our theoretical knowledge of turbulence but also for addressing practical challenges in various scientific and industrial domains—including the processing, transformation, and design of advanced materials.

The purpose of this special issue is to bring together contributions from leading researchers in fluid dynamics, with a particular emphasis on theoretical, numerical, and experimental approaches to turbulent flow. Each article is expected to demonstrate a clear connection—either from a fundamental or applied standpoint—to the fields of materials science and processing. This may include, but is not limited to, heat and mass transport in material production systems, flow-assisted material transformation, plasma-material interactions, and turbulence effects in the synthesis or treatment of materials.

There are no formal restrictions on article length, allowing contributors the freedom to present their findings in comprehensive detail. We welcome both full-length research articles and review papers that align with the following themes. This special issue will focus on the following areas:
1. Analytical approaches to ideal fluid flow equations :Explorations of exact or approximate solutions to ideal fluid models, with an emphasis on how such approaches enhance our understanding of flow behavior relevant to material processing environments.
2. Theoretical modeling of Newtonian fluid turbulence: Analyses that contribute to the theoretical framework of Newtonian flows, particularly where the resulting flow dynamics influence thermal or mechanical processing of materials.
3. Computational solutions for ideal fluid turbulence: Numerical investigations of ideal flow turbulence using advanced computational techniques, with demonstrated implications for processing environments such as melt flows or inert gas dynamics.
4. Numerical modeling of Newtonian fluid dynamics: Simulations of turbulent Newtonian flows in scenarios that mirror those encountered in materials manufacturing, such as casting, extrusion, or chemical vapor deposition.
5. Instabilities and bifurcation phenomena in fluid flows modeled with stochastic forcing: Studies addressing the onset of instabilities through stochastic extensions of the Euler equations, particularly where such instabilities play a role in the microstructure evolution of materials.
6. Turbulence onset in Newtonian fluids through stochastic modeling: Development of stochastic models capturing the transition to turbulence, with applications in controlling or predicting flow conditions in materials processing operations.
7. Free and forced convection in single-phase and multiphase flows within technical systems: Research examining convection-driven flow behavior in systems used for materials synthesis, such as furnaces, reactors, or multiphase slurry processes.
8. Experimental analysis of heat and mass transfer in single-phase and multiphase systems: Empirical investigations that elucidate heat and mass exchange mechanisms under turbulent flow, with relevance to enhancing efficiency in thermal treatment or chemical processing of materials.
9. Plasma, single-phase, and multiphase flow interactions - experiments and theoretical models: Studies integrating fluid mechanics with plasma physics to better understand plasma-assisted material synthesis or etching processes, highlighting both experimental findings and mathematical models.
