RADIANT HEAT AND SURFACE ROUGHNESS EFFECTS IN THE NUMERICAL MODELLING OF TUNNEL FIRES ---PAPERS PRESENTED AT THE 6TH INTERNATIONAL SYMPOSIUM ON THE AERODYNAMICS AND VENTILATION OF VEHICLE TUNNELS, DURHAM, 27-29 SEPT 1988

This paper describes additions to the three dimensional, time dependent, numerical model jasmine described at the previous symposium. Improvements to account for the effects of radiant heat transfer and of momentum and convective heat loss to rough surfaces have been made and fiezlmayer's experimental fire tests conducted in a disused railway tunnel used to evaluate their effectiveness.(a)
