TL;DR: In this paper, the influence of the piston effect in the longitudinal ventilation system of subway tunnels using numerical methodologies is analyzed using Computational Fluid Dynamics (CFD) in order to simulate and analyze in detail the flow patterns associated to this effect.

TL;DR: In this paper, a numerical 3D simulation of a longitudinal ventilation system (LVS) is developed to analyze the fire behaviour inside a road tunnel, where a total number of 24 reversible jet fans are installed in groups of three, nearly equally spaced over the length of the tunnel.

TL;DR: In this article, a CFD methodology involving structure motion and dynamic re-meshing has been optimized and applied to simulate the unsteady flow through normal triangular cylinder arrays with one single tube undergoing either forced oscillations or self-excited oscillations due to damping-controlled fluidelastic instability.

TL;DR: An exhaustive analysis of the influence of solidity, blade Reynolds number and airfoil geometry on the performance of a straight-bladed vertical axis wind turbine has been performed using a methodology based on streamtube models.

TL;DR: In this paper, the authors focused on the analysis of the dynamic and periodic interaction between both fixed and rotating blade rows in a single stage, low-speed axial fan with inlet guide vanes.
