Human convective boundary layer and its interaction with room ventilation flow

This study investigates the interaction between the human convective boundary layer (CBL) and uniform airflow with different velocity and from different directions. Human body is resembled by a thermal manikin with complex body shape and surface temperatur ...

Wind-tunnel experiments of thermally-stratified turbulent boundary layer flow over a wall-mounted 2-D block

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Turbulent boundary-layer flows over complex topography have been extensively studied in the atmospheric sciences and wind engineering communities. The upwind turbulence level, the atmospheric thermal stability and the shape of the topography as well as sur ...

Sensor placement for predicting airflow around buildings to enhance natural ventilation

Ian Smith, Maria Papadopoulou

It is a challenge to design buildings that are both energy efficient and healthy. The factors that contribute to energy efficient and healthy buildings are related to both indoor and outdoor conditions. For example, the airflow around naturally ventilated ...

Benchmark Models for Air Conditioned Residential Buildings in Hot Humid Climate

Shady Galal Mohamed Attia

This study reports the results of a recent field survey for residential apartment buildings in Egypt. The aim of the survey is to create representative building energy models. Two building performance simulation models are created reflecting the average en ...

A facile approach for controlling the orientation of one-dimensional mesochannels in mesoporous titania films

Paul Joseph Dyson, Zhaofu Fei, Yi Wang

Controlling of the orientation of mesochannels in mesostructured thin films is important for the development of novel molecular devices and, in particular, generating vertically aligned mesochannels with respect to the substrate plane is extremely challeng ...

Air Side Contamination in Solid Oxide Fuel Cell Stack Testing

Jan Van Herle, Christian Ludwig, Aïcha Hessler-Wyser, Zacharie Wuillemin, Josef Andreas Schuler, Christian Gehrig

Solid Oxide Fuel Cells (SOFCs) are likely candidates for electricity production with high efficiency and promise reasonable fuel tolerance. While fuel impurities are known anode poisons, less attention is brought to air-purity, especially to air-side conta ...

Atmospheric Boundary Layer Dynamics of Transitional Flows over Complex Terrain

Daniel Nadeau

Recent advances in boundary-layer meteorology are beginning to allow the study of atmospheric flow phenomena that have previously been poorly understood. In this dissertation, we study the effects of complex terrain and unsteady regimes on the atmospheric ...

Optimisation of Buildings Daylight Availability

Jérôme Henri Kämpf, Darren Robinson, Marylène Montavon

Many researchers have the goal of improving buildings daylight availability in order to decrease the HVAC energy intake. Indeed by achieving/identifying sustainable urban forms and their design concepts, the benefits of the solar radiation can be of threef ...

Tracer gas measurement of airflow rates in rooms with several air-handling units and large recirculation rates

Claude-Alain Roulet

Methods to measure airflow rates using tracer gas in single air handling units are well known. In some buildings however, in particular in Singapore, rooms are often ventilated with two or more units and present large recirculation rates. Large recirculati ...
