Title: Evaluation of mean velocity and mean speed for test ventilated room from RANS and LES CFD modeling (Open Access)
Keywords: CFD modeling, Conversion procedures, Mean velocities, Nielsen, Reynolds-averaged-navier-stokes approaches, Turbulence kinetic energy, Velocity components, Ventilated room

Abstract: The paper presents and discusses data for the ventilation airflow in an isothermal room corresponding to the Nielsen et al. (1978) test computed with Large Eddy Simulation (LES) and Reynolds-Averaged Navier-Stokes (RANS) approaches. As LES computations provide directly both the speed and velocity components data, the difference between the mean speed and mean velocity values is computed and discussed. For the RANS computations that give the mean velocity data only, application of the velocity-to-speed conversion procedure based on the turbulence kinetic energy field provided by a turbulence model resulted in accurate mean speed evaluation
