Windtunnel modelling of torch fires (final report)
report
Five European Institutes have been cooperating in the project ’Physical Modelling of Torch Fires’ in which the influence of flames on its surroundings is studied. In the framework of this project TNO Institute of Environmental and Energy Technology has applied small scale modelling of flames in one of their windtunnels. The aim of the experiments is to find proper scaling rules with respect to temperature and heat flux of flames. To this end 7 out of the 10 field measurements performed by Risp, Denmark have been repeated in the windtunnel on scales 1:10 and 1:25 (3 out of these 7). The shape of the flames, temperature profiles and heat fluxes of both model and field scale have been compared. The field scale mean wind velocities range from 2.2 to 5.2 m/s. The ratio between the gas exit velocity and the mean wind velocity range from 4 to 32
