RANS-URANS in axial compressor, a design methodology
, 2011 Turbomachinery flows are inherently unsteady. Until now during the design process, unsteadiness has been neglected, with resort merely to steady numerical simulations.

Women, Crime, and Law in Latin America's Nineteenth Century
History Compass, Volume 24, Issue 4, August 2026.ABSTRACT This article examines the literature on women as perpetrators of crime in 19th‐century Latin America, a topic largely overlooked in historical scholarship. While most studies focus on women as victims of domestic or sexual violence, this work explores women as perpetrators of crime, specifically reproductive crimes (abortion and infanticide ...

DNS–URANS comparison study on cough-induced flow and particles in a large-scale circulation [PDF]
Purpose The purpose of this study is to perform direct numerical simulation (DNS) and unsteady Reynolds-averaged Navier–Stokes simulation (URANS) of cough-induced flow and particles in a large-scale circulation (LSC) to assess the performance and ...

Energy Science &Engineering, Volume 14, Issue 7, Page 3324-3345, July 2026.Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake
Wind Energy, Volume 29, Issue 6, June 2026.ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.
