On The Computational Efficiency Of Les And Hybrid Rans-Les Models In Building Aerodynamics, Aly Mousaad Aly, Faiaz Khaled
On The Computational Efficiency Of Les And Hybrid Rans-Les Models In Building Aerodynamics, Aly Mousaad Aly, Faiaz Khaled
Faculty Publications
Large-eddy simulation (LES) has proven to offer superior accuracy in regards to predicting surface pressures compared to the Reynolds-averaged Navier Stokes (RANS) models. However, the primary impediment is the high computational cost associated with LES. The authors attempt to investigate the computational cost and accuracy by employing different sub-grid scale (SGS) models in LES and hybrid RANS-LES models. One of the prerequisites of accurate pressure estimations is to ensure a horizontally homogeneous empty computational domain. This study aims to compare the computational competence qualitatively and quantitatively using an empty domain in regards to the ability to maintain horizontal homogeneity. The …

With the sustainability movement, vegetated building envelopes are gaining more popularity. This requires special wind effect investigations, both from sustainability and resiliency perspectives. The current paper focuses on wind load estimation on small- and full-scale trees used as part of green roofs and balconies. Small-scale wind load assessment was carried out using wind tunnel testing in a global-effect study to understand the interference effects from surrounding structures. Full-scale trees were investigated at a large open-jet facility in a local-effect study to investigate the wind-tree interaction. The effect of Reynolds number combined with shape change on the overall loads measured at …
Following Industry's Leed : Municipal Adoption Of Private Green Building Standards, Sarah B. Schindler
Following Industry's Leed : Municipal Adoption Of Private Green Building Standards, Sarah B. Schindler
Faculty Publications
Local governments are beginning to require new, privately constructed and funded buildings to be “green” buildings. Instead of creating their own, locally-derived definitions of green buildings, many municipalities are adopting an existing private standard created by members of the building industry: LEED (Leadership in Energy and Environmental Design). This Article explains and assesses the privately promulgated LEED standards. It argues that the translation of LEED standards, which were intended to be voluntary, into law raises several theoretical and practical problems. Specifically, private green building ordinances that rely on LEED do not ensure a reduction in the negative local environmental impacts …
Optimal Width And Depth For Maximum Breaking Load Of Wood Beams, Steven H. Bullard, Vikram Yadama
Optimal Width And Depth For Maximum Breaking Load Of Wood Beams, Steven H. Bullard, Vikram Yadama
Faculty Publications
The strength of solid wood beams is an important property to consider in construction. Such beams do not receive further primary processing after leaving the sawmill, and their quality and strength properties are therefore determined by their initial, primary breakdown at the sawmill. The most efficient means of controlling the quality of solid wood beams is thus at the sawmill level. This paper presents a method of determining the width and depth of solid beams that will maximize breaking load.
