Determining the venting efficiency of simple chimneys for buoyant plumes

Autor: Burridge, HC, Sehmbi, G, Fiuza Dosil, D, Hughes, GO

Publikováno v: 38th AIVC Conference

We present preliminary results from an examination of the capture and venting of a buoyant plume by a chimney. The aim is to enable improved management of indoor pollutant sources – for instance, the plume rising from a cooking pan in a kitchen or

A comparison of line-sources of buoyancy placed near and far from a wall

Autor: Parker, D, Burridge, HC, Partridge, J, Linden, P

Publikováno v: 38th AIVC Conference: Ventilating healthy low-energy buildings

Experiments are presented on turbulent buoyant free - line and wall plumes, whereby the buoyancy source is emitted from a horizontal line source, in one case free of the presence of a wall and in the other placed immediately adjacent to a wall. The d

We present simultaneous two-dimensional velocity and scal ar concentrations measured on a central vertical plane in a turbulent plume. We use an edg e-detection algorithm to determine the scalar plume edge, and compare the data obtain ed in both a fi

The transport of liquids in softwood: timber as a model porous medium

Autor: Burridge, HC, Wu, G, Reynolds, T, Shah, DU, Johnston, R, Scherman, OA, Ramage, MH, Linden, PF

Timber is the only widely used construction material we can grow. The wood from which it comes has evolved to provide structural support for the tree and to act as a conduit for fluid flow. These flow paths are crucial for engineers to exploit the fu

Vertically distributed wall-sources of buoyancy. Part 2: Unventilated and ventilated confined spaces

We examine the flow resulting from a vertically distributed wall-source plume in both an unventilated and ventilated space. First, we present experimental ambient buoyancy measurements for an unventilated ‘filling box’ where the developing ambien

Predictive and retrospective modelling of airborne infection risk using monitored carbon dioxide

Autor: Shiwei Fan, Paul Linden, Catherine J. Noakes, Roderic L. Jones, H. C. Burridge

The risk of long range, herein `airborne', infection needs to be better understood and is especially urgent during the current COVID-19 pandemic. We present a method to determine the relative risk of airborne transmission that can be readily deployed

Publikováno v: Reynolds, T P S, Burridge, H C, Johnston, R, Wu, G, Shah, D U, Scherman, O A, Linden, P F & Ramage, M H 2018, ' Cell Geometry across the Ring Structure of Sitka Spruce ', Journal of the Royal Society, Interface, vol. 15, no. 142, 20180144 . https://doi.org/10.1098/rsif.2018.0144

For wood to be used to its full potential as an engineering material, it is necessary to quantify links between its cell geometry and the properties it exhibits at bulk scale. Doing so will make it possible to predict timber properties crucial to eng
