- Abstract
- The paper presents measurements of the heat flux distribution to the surfaceof four square towers exposed to buoyant turbulent flames. The steel towers represent an idealisation of a rack storage configuration at reduced scale. Each tower was 1.8 m high and 0.3 m x 0.3 m wide. The fuel was supplied from a circular gas burner at the floor. Three different gaseios fuels were used: carbon monoxide (CO), propane (C₃H₈), and propylene (C₃H₆). These fuels cover a wide range of flame sootiness resulting in distinctly different flame heat fluxes. At the same overall heat release rates the peak heat fluxes from C₃ H₆ flames were twice those from CO flames, whereas the peak heat fluxes from C₃H₆ flames were 2.8 times those from CO flames. Heat fluxes were measured by thermocouples spot-welded to the back of the steel sheets. They were measured at 51 different locations. This measurement method turns out to be simple, accurate and robust in addition to being inexpensive.
