Special Issue Information

Dear Collegues,

This Special Issue delves into the enigma of turbulent flow, a persistent conundrum in classical physics and engineering. Even in the present day, comprehending turbulence at its core and crafting precise models for turbulent flows remain formidable challenges. Nevertheless, recent breakthroughs, propelled by the synergy of high-performance computing, sophisticated numerical methods, and advanced analysis techniques, have illuminated fresh perspectives on the intricate nature of turbulence.

Within the pages of this Special Issue, we aim to capture the latest pioneering advancements propelling the field forward. We extend an invitation for both original research contributions and comprehensive review articles, elucidating the latest strides made in this domain. The scope of this Special Issue encompasses theoretical explorations, computational simulations, and experimental investigations of turbulence across a wide spectrum of flow scenarios. The topics of interest include, but are not limited to, the following:

  • High-fidelity numerical simulations that unveil novel physical insights;
  • Innovative computational techniques tailored for simulation and modeling;
  • The application of data-driven methodologies, such as machine/deep learning, for analysis and modeling;
  • Explorations into turbulence control, modeling, and engineering applications.

By amalgamating these cutting-edge accomplishments and offering insights into the challenges that endure, this Special Issue aims to showcase the dynamic nature of contemporary turbulence research. Our objective is to provide a snapshot of the current state of the art, serving as a source of inspiration for future advances in our comprehension and capabilities concerning turbulent flow. We enthusiastically welcome specialized contributions, as well as those offering a broader overview of this multifaceted field.

Data obtained using direct numerical simulations (DNS) of pressure-driven turbulent channel flow are studied in the range 180 Reτ 10,000. Reynolds number effects on the mean velocity profile (MVP) and second order statistics are analyzed with a view of finding logarithmic behavior in the overlap region or even further from the wall, well in the boundary layer’s outer region. The values of the von Kármán constant for the MVPs and the Townsend–Perry constants for the streamwise and spanwise fluctuation variances are determined for the Reynolds numbers considered. A data-driven model of the MVP, proposed and validated for zero pressure-gradient flow over a flat plate, is employed for pressure-driven channel flow by appropriately adjusting Coles’ strength of the wake function parameter, Π. There is excellent agreement between the analytic model predictions of MVP and the DNS-computed MVP as well as of the Reynolds shear stress profile. The skin friction coefficient Cf is calculated analytically. The agreement between the analytical model predictions and the DNS-based computed discrete values of Cf is excellent. Full article
