Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

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

A methodology to implement non-reflecting boundary conditions for turbomachinery
applications, based on characteristic analysis is described in this paper. For these …

Over the past two decades high-fidelity simulations have become feasible for most main gas
path turbomachinery components. This paper introduces the key challenges of simulating …

An intermittency model that is formulated in local variables is proposed for representing
bypass transition in Reynolds-Averaged Navier-Stokes (RANS) computations. No external …

This article reports a procedure to implement as well as to validate non‐reflecting boundary
conditions applied for turbomachinery simulations, using Navier–Stokes characteristic …

Transition from laminar flow to turbulent flow is of great practical interest as it occurs in many
engineering flows and often plays a critical role in aerodynamics and heat transfer …

The wake/boundary–layer interactions over a cylinder/airfoil configuration are investigated
using hydrogen bubble visualization and time-resolved particle image velocimetry. The …

The central aim of the paper is to apply and assess a nonlinear optimal control strategy to
suppress bypass transition, due to bimodal interactions [TA Zaki and PA Durbin,“Mode …

This paper examines the transition process in a boundary layer on a rotor blade under the
impingement of an inlet guide vane wake. The effects of wake strengths and the reduced …
