LES over RANS in building simulation for outdoor and indoor applications: A foregone conclusion?
Bert Blocken,Bert Blocken +1 more
TL;DR: Why RANS is still frequently used and whether this is justified or not is illustrated by examples for five application areas in building simulation: pedestrian-level wind comfort, near-field pollutant dispersion, urban thermal environment, natural ventilation of buildings and indoor airflow.

Application of computational fluid dynamics in building performance simulation for the outdoor environment: an overview
TL;DR: An overview of the application of computational fluid dynamics (CFD) in building performance simulation for the outdoor environment, focused on four topics: (1) pedestrian wind environment around buildings, (2) wind-driven rain on building facades, (3) convective heat transfer coefficients at exterior building surfaces and (4) air pollutant dispersion around buildings as discussed by the authors.

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.

Enhancements of the simple method for predicting incompressible fluid flows
J. P. Van Doormaal,G. D. Raithby +1 more
TL;DR: The performances of SIMPLE, SIMPLER, and SIMPLEC are compared for two recirculating flow problems and several modifications to the method are shown which both simplify its implementation and reduce solution costs.

The flow around a surface-mounted cube in uniform and turbulent streams
Ian P. Castro,A. G. Robins +1 more
TL;DR: In this article, an experimental investigation of the flow around surface mounted cubes in both uniform, irrotational and sheared, turbulent flows is described, and comparisons with the somewhat sparse measurements of previous workers are made and the relevance of recent theoretical attempts to describe the flow, as opposed to numerical calculation techniques to predict it, is briefly discussed.

3-D numerical simulation of airflow around a cubic model by means of the k-ϵ model
Shuzo Murakami,Akashi Mochida +1 more
TL;DR: In this article, a three-dimensional numerical simulation of airflow around a cubic model using the k-ϵ two-equation turbulence model is investigated, and the accuracy of these simulations is examined by comparing the predicted results with wind-tunnel experiments conducted by the authors.
