SIMULATION OF HEAT TRANSFER FROM CANOPY SURFACES USING LOW-REYNOLDS NUMBER k-E MODEL
Autor: Sivaraja Subramania Pilla, Ryuichiro Yoshie
Publikováno v: Journal of Urban and Environmental Engineering, Vol 8, Iss 2, Pp 186-191 (2014)
This study focuses on the Convective Heat Transfer Coefficient (CHTC) from urban building surfaces by numerical simulation. The heat transfer effects because of various geometrical and physical properties of urban areas exhibits a differential heatin

FLOW VELOCITY AND SURFACE TEMPERATURE EFFECTS ON CONVECTIVE HEAT TRANSFER COEFFICIENT FROM URBAN CANOPY SURFACES BY NUMERICAL SIMULATION
Autor: Sivaraja Subramania Pillai, Ryuichiro Yoshie
Publikováno v: Journal of Urban and Environmental Engineering, Vol 7, Iss 1, Pp 74-81 (2013)
This study investigates the effect of flow velocity and building surface temperature effects on Convective Heat Transfer Coefficient (CHTC) from urban building surfaces by numerical simulation. The thermal effects produced by geometrical and physical

Large-eddy simulation of flow and pollutant dispersion in a 3D urban street model located in an unstable boundary layer
Autor: Ryuichiro Yoshie, Guoyi Jiang
Publikováno v: Building and Environment. 142:47-57
Large-eddy simulation (LES) based on the standard Smagorinsky model was employed to simulate microscale pollutant dispersion in a three-dimensional urban street model in an unstable boundary layer. First, an inflow turbulence generation technique bas

Effect of atmospheric stability on air pollutant concentration and its generalization for real and idealized urban block models based on field observation data and wind tunnel experiments
Autor: Ryuichiro Yoshie, Tingting Hu
Publikováno v: Journal of Wind Engineering and Industrial Aerodynamics. 207:104380
Near-surface atmospheric stability has a large influence on air pollutant diffusion in urban canopy. However, few systematic and quantitative studies have analyzed the effects of atmospheric stabilities on urban air pollutant concentration due to the

Side ratio effects on flow and pollutant dispersion around an isolated high-rise building in a turbulent boundary layer
Autor: Guoyi Jiang, Ryuichiro Yoshie
Publikováno v: Building and Environment. 180:107078
Large-eddy simulations were performed to investigate side ratio (SR) effects on flow and dispersion around an isolated high-rise building. Four cross sections were considered with SR ranging from 0.25 to 1.5. Three pollutants were released from the g
