CFD simulation of cross-ventilation for a generic isolated building : impact of computational parameters
TL;DR: In this paper, a series of coupled 3D steady RANS simulations for a generic isolated building are validated based on detailed wind tunnel experiments with Particle Image Velocimetry, and the impact of a wide range of computational parameters is investigated, including the size of the computational domain, the resolution of computational grid, the inlet turbulent kinetic energy profile of the atmospheric boundary layer, the turbulence model, the order of the discretization schemes and the iterative convergence criteria.

Simulation of effect of wind barriers on airflow.
TL;DR: In this article, the authors developed a quantitative, theoretical simulation of airflow normal to narrow wind barriers of various porosities and, when possible, verify the results using experimental data, using finite difference methods having a combination of upwind and central difference schemes.

Computational and wind tunnel modelling of mean wind loads on the Silsoe structures building
Peter Richards,R.P. Hoxey +1 more
TL;DR: In this paper, results from both wind-tunnel and computational modelling of mean wind loads on the Silsoe Structures Building are compared with full-scale data and it is shown that systematic differences exist between windtunnel data obtained at BRE (U.K.), UWO (Canada) and the University of Auckland (NZ).

Prediction of the wind-generated pressure distribution around buildings
TL;DR: In this paper, the use of computational methods to predict wind-generated pressure distributions around buildings is investigated, which are needed for the prediction of natural ventilation in the buildings, and the accuracy of the predicted pressure distribution is found to be acceptable.
