The present review shows a summary of current trends in high-fidelity simulations of
turbulent flows in moderately complex geometries. These trends are put in the historical …

For adverse-pressure-gradient turbulent boundary layers, the study of integral skin-friction
contributions still poses significant challenges. Beyond questions related to the integration …

A horizontal water channel facility was built to study particle dynamics in a turbulent flow.
The channel is sufficiently long to produce fully developed turbulence at the test section, and …

This paper presents a comprehensive three-dimensional Direct Numerical Simulation (DNS)
investigation of flow characteristics over a roughened wall in a duct, exploring bulk Reynolds …

The Euler characteristic (EC) is a powerful topological descriptor that can be used to quantify
the shape of data objects that are represented as fields/manifolds. Fast methods for …

Turbulent heat transfer in a square duct, where a finite section of a single duct boundary is
heated with an infinitely thin foil, was analyzed with LES and DNS approaches. Both …

The behavior of turbulent flows remains a significant unsolved problem in physics. Recently,
a large quantity of effort has been directed toward understanding the non-linear interactions …

Purpose Hydrodynamic forces and efficiency of bare propeller and ducted propellers with a
wide range of advance ratio (J) and attack angle (θ) are examined. The thrust and torque …

The transition route from laminar to turbulent flow in a magnetohydrodynamic (MHD) duct
with a square cross-section is investigated in the limit of low magnetic Reynolds number. In …

This research focuses on the identification and causality analysis of coherent structures that
arise in turbulent flows in square and rectangular ducts. Coherent structures are first …
