Modeling wall turbulence remains a major challenge, as a sufficient physical understanding
of these flows is still lacking. In an effort to move toward a physics-based model, AA …

While data-based approaches were found to be useful for subgrid scale (SGS) modeling in
Reynolds-averaged Navier-Stokes (RANS) simulations, there have not been many attempts …

Log-layer mismatch refers to a chronic problem found in wall-modeled large-eddy simulation
(WMLES) or detached-eddy simulation, where the modeled wall-shear stress deviates from …

According to Townsend's attached eddy hypothesis (AEH), a boundary layer flow is
comprised of wall-attached eddies, but to extract the part of the flow whose statistical …

At high Reynolds numbers, the logarithmic range in wall-bounded flows spans many scales.
An important conceptual modeling framework of the logarithmic range is Townsend's …

At transcritical conditions, the transition of a fluid from a liquidlike state to a gaslike state
occurs continuously, which is associated with significant changes in fluid properties …

The kinematics of a fully developed passive scalar is modelled using the hierarchical
random additive process (HRAP) formalism. Here,'a fully developed passive scalar'refers to …

The attached-eddy model (AEM) is one of the most successful coherent-structure-based
phenomenological models in wall turbulence. In the classical AEM, the probability density of …

This work introduces a mathematical approach to analysing the polymer dynamics in
turbulent viscoelastic flows that uses a new geometric decomposition of the conformation …

Eddies affect the motion of particles within the turbulence boundary layer on different length
and velocity scales. Attached eddies, which extend to the wall, are primarily responsible for …
