An Experimental and Numerical Approach to Multifunctional Urban Surfaces through Blue Roofs

چکیده
Uncontrolled urban growth causes a number of problems associated with land use, stormwater management and energy generation. Sustainable Urban Drainage Systems (SUDS) are positioned as an alternative to traditional constructive solutions, contributing towards the generation multifunctional spaces for efficient consumption reduction. Nevertheless, this combined goal calls deeper understanding heat transfer processes that govern temperature performance in SUDS order be further validated infrastructure house renewable elements. This study intends determine thermal properties two types blue roofs under extreme conditions (wet dry), depicting operation features their layers comparing performances based on materials used. With aim, hybrid experimental methodology, combining laboratory numerical modelling, was designed using standardized equipment (ISO 8990:1994 ASTM C1363-05), improving previous methods proposed SUDS. The section expanded clay improved hydraulic capacity by 4.8%. without increased its transmittance value 64.9% wet conditions. It also found presence water equivalent conductivity both sections 60%.

This paper tries to achieve a solution for problems that concern condensation around a flat plate, circular and elliptical tube in by numerical and analytical methods. Also, it calculates entropy production rates. At first, a problem was solved with mesh dynamic and rational assumptions; next it was compared with the numerical solution that the result had acceptable errors. An additional suppor...
متن کاملNumerical Analysis and Experimental Study of Hard Roofs in Fully Mechanized Mining Faces under Sleeve Fracturing
Sudden falls of large-area hard roofs in a mined area release a large amount of elastic energy, generate dynamic loads, and cause disasters such as impact ground pressure and gas outbursts. To address these problems, in this study, the sleeve fracturing method (SFM) was applied to weaken a hard roof. The numerical simulation software FLAC3D was used to develop three models based on an analysis ...

The research focused on the experimental evaluation of Photovoltaic (PV) – green roofs under Mediterranean climate summer conditions. Two autochthonous plants, Gazania rigens and Sedum clavatum, were selected for the PV-green systems while a PV-gravel configuration was used as the reference roof. The above mentioned roofing systems were developed and tested at the University of Lleida, in Spain...
