Aerodynamic investigations of ventilated brake discs.

The heat dissipation and performance of a ventilated brake disc strongly depends on the aerodynamic characteristics of the flow through the rotor passages. The aim of this investigation was to provide an improved understanding of ventilated brake rotor flow phenomena, with a view to improving heat dissipation, as well as providing a measurement data set for validation of computational fluid dynamics methods. The flow fields at the exit of four different brake rotor geometries, rotated in free air, were measured using a five-hole pressure probe and a hot-wire anemometry system. The principal measurements were taken using two-component hot-wire techniques and were used to determine mean and unsteady flow characteristics at the exit of the brake rotors. Using phase-locked data processing, it was possible to reveal the spatial and temporal flow variation within individual rotor passages. The effects of disc geometry and rotational speed on the mean flow, passage turbulence intensity, and mass flow were determined. The rotor exit jet and wake flow were clearly observed as characterized by the passage geometry as well as definite regions of high and low turbulence. The aerodynamic flow characteristics were found to be reasonably independent of rotational speed but highly dependent upon rotor geometry

Motivations and environmental practices of urban gardeners : the cases of Ljubljana, London and Milan

In this paper, the phenomenon of urban gardening is observed both from a sociological and an environmental perspective. The analysis focuses on motivations and environmental practices of different groups of urban gardeners in Ljubljana, London and Milan: home food gardeners and allotment gardeners in public and private plots

Constructed wetlands and solar-driven disinfection technologies for sustainable wastewater treatment and reclamation in rural India: SWINGS project

The largest wastewater treatment plant consists of a high-rate anaerobic system, followed by vertical and horizontal subsurface flow constructed wetlands (HFCW) with a treatment area of nearly 1900 sq m and a final step consisting of solar-driven anodic oxidation and ultraviolet disinfection units allowing direct reuse of the treated water. and even act as a revenue generator. The effluent of the HFCW is collected in a 1.8 m deep well, from where about 10% of the final effluent is pumped and disinfected using the two solar-powered units. The implementation of the systems under the umbrella of the SWINGS project will provide opportunity to tes advanced CW configurations operating to meet local needs.Peer ReviewedPostprint (author's final draft
