Transient Simulation of Airflow and Pollutant Dispersion Under Mixing Flow and Buoyancy Driven Flow Regimes in Residential Buildings
The distribution of airflow in a residential building varies with the periodic operation of a heating, ventilating and airconditioning (HVAC) system. Depending on the HVAC fan operation, mixing airflow (fan ON) or stratified airflow (fan OFF) occurs in the space. The objectives of this study are 1) to examine the time needed for room air to stabilize after a central ventilation fan turns ON/OFF...
متن کاملA Wind-driven Hydrodynamic and Pollutant Transport Model
ABSTRACT A program is developed that includes two hydrodynamic models, a 2D depth-averaged (2DH) and a Quasi-3D (Q3D), and a pollutant transport model that uses a 1 order upwinding and a 3 order QUICKEST numerical schemes. Several tests were performed in two test basins in order to examine the performance of the above models. The Q3D model is successfully applied to Lake Ontario, using a 4-km-s...

15 صفحه اولUrban Pollutant Transport and Infiltration into Buildings Using Perfluorocarbon Tracers
People spend the majority of their time indoors and therefore the quality of indoor air is worthy of investigation; indoor air quality is affected by indoor sources of pollutants and from pollutants entering buildings from outdoors. In this study, unique perfluorocarbon tracers were released in five experiments at a 100 m and ~2 km distance from a large university building in Manchester, UK and...
متن کاملInverse Estimation of Soil Hydraulic and Solute Transport Parameters from Transient Field Experiments: Heterogeneous Soil
While inverse parameter estimation techniques for determining key parameters affecting water flow and solute transport are becoming increasingly common in saturated and unsaturated zone studies, their application to practical problems, such as irrigation, have received relatively little attention. In this article, we used the Levenberg–Marquardt optimization algorithm in combination with the HY...
