This study aims to investigate and clarify the effects of roadside trees and moving automobiles onoutdoor airflow distribution, turbulent diffusion of air pollutants and thermal environment within streetcanyons by means of the results obtained from field measurements in the central part of Sendai city,Japan. The detailed field measurements were carried out in the summer of 2006, at two streets withdifferent densities of roadside trees and traffic volume. The microclimate and NOX concentrations as wellas traffic volume were measured.
In recent years, occupants conduct various behaviors in the appurtenant dressing room, so it isimportant to know the amount of modern moisture production in the appurtenant dressing room.Investigation data showed amount of moisture production caused by the behaviors in the dressingroom did not differ between males and females, and amount of moisture production caused by washingclothes and drying clothes did differ depending on the equipment.
Urban development is unavoidable as the result of country’s economic growth. Without a careful planning, a city may cause environment destruction. Singapore is known to have the best environmental quality in the world. However, in the previous research on
This paper describes an investigation into the ventilation performance and the indoor air quality of a portable classroom. Both field measurements and numerical simulations based on CFD (Computational Fluid Dynamics) technology were used. Field measurements in an unoccupied classroom used smoke to visualize the flow pattern, and hot-film probes to quantitatively measure air velocity. These field measurements provided the boundary conditions for CFD simulations and the experimental data to examine the accuracy of the CFD simulations.
