Research ArticleOpen accessIn the author namesUse of the Nere Pod (Parkia Biglobosa) for the Improvement of Mechanical Properties of SoilsSinko Banakinao, Sonnou Tiem, Kodjo Attipou et al.Buildings made of unbaked clay have some advantage in terms of production cost. However, they have some inconveniences concerning their mechanical performance, particularly their resistance to weather. The objective of this study is to minimize these disadvantages and to maximize the benefits of such buildings to make them more viable. For this purpose, a method based on a traditional practice … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 16 Feb 2017 · 7,853 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntegrated Modeling Framework for Highway Traffic Pollution Estimation and DispersionShu Yang, Yao-Jan Wu, John WoolschlagerAir quality is of great concern to the public. Airborne pollutants, such as carbon monoxide (CO), carbon dioxide (CO2) and Particulate Matter (PM), negatively impact people’s living conditions. In particular, vehicular exhaust is a major source of these pollutants. Extensive previous research has contributed to modeling traffic pollutant emission. Popular approaches include computational simulation-based methods, which have been dominant in … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 13 May 2016 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the author namesON THE RELIABILITY OF REYNOLDS-AVERAGED NAVIER STOKES PREDICTION OF MEAN FLOW CHARACTERISTICS OF A RECTANGULAR TURBULENT JET IN CROSSFLOWE. Khali, Y. F. YaoA jet of fluid discharging into a cross stream, also known as Jet In Crossflow (JICF), has received many experimental and numerical investigations. In addition to the fundamental understanding of three-dimensional mixing and shear flow characteristics, the fluid dynamics research community often regarded it as a benchmark test case for validating turbulence models. Although many authors considered the canonical case … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the author namesTHE IMPROVEMENT OF THE COMPUTATIONAL PERFORMANCE OF THE ZONAL MODEL POMA USING PARALLEL TECHNIQUESYao Yu, Ahmed Cherif Megri, Kenneth M. Flurchick, Dukka Bahadur K.C.The zonal modeling approach is a new simplified computational method used to predict temperature distribution, energy in multi-zone building and indoor airflow thermal behaviors of building. Although this approach is known to use less computer resource than CFD models, the computational time is still an issue especially when buildings are characterized by complicated geometry and indoor layout of furnishings. Therefore, … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 12 Apr 2014 · 7,736 accessesView PDFCite
Research ArticleOpen accessIn the author namesUSE OF COMPUTATIONAL FLUID DYNAMIC TO PREDICT AIRFLOW AND TEMPERATURE DISTRIBUTION IN A RESIDENTIAL BUILDING WITH AN UNDER FLOOR AIR DISTRIBUTION SYSTEMAbd Alnasser Almate A. Ali, Ahmed Cherif Megri, Paul A. Dellenback, Yao YuOur objective is to demonstrate the use of Computational Fluid Dynamic (CFD) in building applications. In particular, CFD has been used for temperature and airflow predictions of building spaces conditioned using Under Floor Air Distribution (UFAD) System. The space used is an instrumented laboratory room (old daycare center) located at the University of Wyoming. The use of the CFD simulation … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 11 Apr 2014 · 8,256 accessesView PDFCite
Research ArticleOpen accessIn the author namesILLUMINANCE EVALUATION AND ASSESSMENT AT THREE ELEMENTARY SCHOOLSAhmed Cherif Megri, Yao Yu, Akeel Sobers, Alyssa CooperA simplified model for illuminance prediction has been developed to estimate the indoor level of lighting under artificial lighting. As well, illuminance in several locations of three schools has been measured under several conditions: Blinds up/lights on, blinds up/lights off, blinds down/lights on, blinds down/lights off. The experimental data of the case &#34blinds down/lights on&#34 has been compared to the … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 7,860 accessesView PDFCite
Research ArticleOpen accessIn the author namesA NOVEL PRESSURIZED ZONAL MODEL USING THE MOMENTUM EQUATIONYao Yu, Ahmed Cherif MegriZonal models combine the simplicity of single and multi-zone models with the comprehensiveness of Computational Fluid Dynamics (CFD) models and thus become a better substitute to predict detailed thermal and airflow behaviors in building. Based on a geometric partitioning of a room into a number of subzones, these models give more accurate and detailed results than the single or multi-zone … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 25 Mar 2014 · 8,574 accessesView PDFCite
Research ArticleOpen accessIn the author namesDYNAMIC ENERGY MODELING OF AN EXPERIMENTAL BUILDING EQUIPPED WITH AN UNDERFLOOR AIR DISTRIBUTION (UFAD) SYSTEMYao Yu, Ahmed Cherif MegriIn this study, experimental and simulation studies were performed in a building equipped with an UFAD system in order to investigate the applicability of a new approach designed for prediction of the energy consumption of a residential building with an UFAD system. In this approach, a zonal model, Pressurized zOnal Model with the Air diffuser (POMA), was coupled with a … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 14 Mar 2014 · 8,141 accessesView PDFCite
