Air pressure and wind velocity - modelling ember attack within the urban-rural interface
conference contributionposted on 2011-01-01, 00:00 authored by S Honey, Alexander RolloAlexander Rollo
As population change places pressure on expanding regional and metropolitan urban boundaries, so the threat of bushfire at the rural/urban interface increases. This paper presents a range of 2D and 3D 1:40 and full scale modelling investigations. Various relationships are explored between the urban and rural interface with respect to: air pressure; changes in wind pattern; vectorial velocity; and the deposition of hot ash and firebrand deposits around single story building forms, both as standalone and within an orthogonal array and cul-de-sac relationships.
