The current generation of axial turbomachines is the culmination of decades of experience,
and detailed understanding of the underlying flow physics has been a key factor for …

Transitional–turbulent spots bridge the deterministic laminar state with the stochastic
turbulent state and affect the transition zone length in engineering flows. Turbulent spot …

High-resolution large-eddy simulation is used to investigate the mean and turbulence
properties of a separated flow in a channel constricted by periodically distributed hill-shaped …

an eerie type of chaos can lurk just behind a facade of order, and yet deep inside the chaos
lurks an even eerier type of order.” Douglas Hofstadter Bypass transition to turbulence in …

This review paper surveys some of the progress made to date in the use of machine learning
(ML) for turbulence and heat transfer modeling. We start by identifying the challenges that …

Modern low pressure turbines (LPT) feature high pressure ratios and moderate Mach and
Reynolds numbers, increasing the possibility of laminar boundary-layer separation on the …

Three-dimensional direct numerical simulations (DNS) of flow in a low-pressure turbine
cascade at high angle of attack have been performed. The large angle of attack is found to …

Current models for transition in turbomachinery boundary layer flows are reviewed. The
basic physical mechanisms of transition processes and the way these processes are …

The flow through a compressor passage without and with incoming free-stream grid
turbulence is simulated. At moderate Reynolds number, laminar-to-turbulence transition can …

The effect of a blunt leading edge on bypass transition is studied by numerical simulation. A
mixed direct and large-eddy simulation of a flat plate with a super-ellipse leading edge is …
