Special Issue Information

Dear Colleagues,

This Special Issue of Axioms aims to present and promote recent advances in the mathematical foundations and modern analytical, numerical, and computational methods for the study of fluid dynamics. As fluid flows play a central role in many physical, biological, and industrial processes, the rigorous understanding and modeling of their behavior remain a cornerstone of applied mathematics.

The focus of this Special Issue is on the development of axiomatic frameworks, new theoretical insights, and advanced numerical techniques that involve the mathematical modeling of fluids, whether incompressible, compressible, multiphase, non-Newtonian, or turbulent. Topics of interest include, but are not limited to, the following: the analysis of partial differential equations governing fluid motion; existence and uniqueness results; stability and control of flow systems; numerical schemes for multi-physics and multiscale phenomena; and applications to real-world systems.

This Special Issue also encourages contributions that bridge mathematical fluid dynamics with areas such as optimization, uncertainty quantification, machine learning, and high-performance computing. By assembling contributions from leading researchers and emerging scholars, this Special Issue will offer a snapshot of current trends and challenges, while highlighting open questions and directions for future work.

We look forward to your valuable contributions.

Reliable simulations of any flow require proper preservation of the fundamental principles governing the mechanics of its motion, whether in differential or integral form. When these principles are solved in differential form, discretization schemes introduce errors by transforming the continuous physical domain into a discrete representation that only approximates it. This paper analyzes the numerical performance of the solver for supersonic chemically active flows, rhoCentralRfFoam, using integral conservation principles of mass, momentum, energy, and chemical species as a validation tool in a classical test case with a highly refined mesh under nonlinear pre-established reference conditions. The analysis is conducted on this specific test case; however, the methodology presented here can be applied to any problem under study. It may serve as an a posteriori verification tool or be integrated into the solver’s workflow, enabling automatic verification of conservation at each time step. The resulting deviations are evaluated, and it is observed that the numerical errors remain below 0.25%, even in cases with a high degree of nonlinearity. These results provide preliminary validation of the solver’s accuracy, as well as its ability to capture physically consistent solutions using only information generated internally by the solver for validation. This represents a significant advantage over validation methods that require external comparison with reference solutions, numerical benchmarks, or exact solutions. Full article
