Special Issue Information

Dear Colleagues,

The modeling of fluid flows is an important topic of research due to its connection with chemical and biological processes, physics, engineering, and microfluidics. During the last years, modeling efforts in fluid dynamics (for example, in areas like biofluids, porous media flows, aerodynamics or combustion) have led to new developments in mathematics, in particular in the numerical and analytical advances of PDEs.

We are pleased to invite you to submit works discussing relevant developments and applications of mathematical modeling in fluid dynamics and mechanics. The works can be focused on analytical conceptions, numerical approaches, or a combination of analytical and numerical methods. Experimental works are also welcome, but they should relate to mathematical theories.

This Special Issue aims to present current research in fluid modeling, attracting researchers and serving as a placeholder to concentrate new ideas for the future development of fluid modeling.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Energy formulation of fluids;
  • Variational approaches theory and numerics;
  • Biofluids modeling;
  • Flows in porous media;
  • Combustion theory;
  • Flame propagation modeling;
  • Perturbation approaches;
  • Travelling waves and soliton solutions;
  • Regularity, uniqueness and smoothness of fluid solutions;
  • Higher order parabolic operators in fluid modeling;
  • p-Laplacian, poly-Laplacian and other bizarre operators in fluid modeling;
  • Navier–Stokes equations;
  • Laminar and turbulent flow modeling;
  • Finite element analysis, finite difference method, and finite volume method;
  • Boundary layer theory;
  • Vortex methods;
  • Large eddy simulation;
  • Particle image velocimetry in fluid modeling;
  • Smoothed particle hydrodynamics;
  • Scaling laws and dimensional analysis;
  • Wind tunnel testing and fluid modeling;
  • Wavelet methods for turbulence.

I/We look forward to receiving your contributions.

In this paper, we present a mathematical approach for studying the changes in pressure and temperature variables in flames. This conception extends beyond the traditional second-order Laplacian diffusion model by considering the p-Laplacian operator and a bi-stable reaction term, thereby providing a more generalized framework for flame diffusion analysis. Given the structure of our equations, we provide the boundedness and uniqueness of the solutions in a weak sense from both analytical and numerical approaches. We further reformulate the governing equations in the context of traveling wave solutions, applying singular geometric perturbation theory to derive the analytical expressions of these profiles. This theoretical development is complemented by numerical assessments, which not only validate our theoretical predictions, but also optimize the traveling wave speed to minimize the error between numerical and analytical solutions. Additionally, we explore self-similar structured solutions. The paper then concludes with a perspective on future research, with emphasis being placed on the need for experimental validation in laboratory settings. Such empirical studies could test the robustness of our model and allow for refinement based on actual measurements, thereby broadening the applicability and accuracy of our findings in practical scenarios.
