ISO 9705 Room-Corner Test & Model simulations
;S.E. Dillom;J,G Quintiere;
Fire Science and Engineering, volume 13, issue 2, 1999, Pages 3~11
New examination of a predictive model for the ISO 9705 room-corner test have been m made for materials studied by L S Fire Laboratories, Italy. The ISO 9705 test subjects wall a and ceiling mounted materials to a comer ignition source of 100 kW for a duration of 10 m minutes; if flashover does not occur this is followed by 300 kW for another 10 minutes. The m materials that did not stay in place during combustion because of melting, dripping, or d distorting were simulated by an adjustment to the material's total available energy. For m mat려als that remain in place the simulation model appears to do well in its prl어ictions. A l large-s떠Ie room test results 뾰 compar벼 with the m여el’s prediction also.
A Study on the Smoldering hazard of Rice bran dust.
Fire Science and Engineering, volume 13, issue 2, 1999, Pages 12~17
We intended to investigate combustion properties of rice bran dust. Combustion properties of h rice bran dust according to size distribution and amount were measured as temperature v variation with time using spontaneous ignition apparatus. Moreover, combustion properties w with blowing or without blowing condition were checked in order to investigate combustion p properties in spontaneous ignition apparatus according to flow condition of air. A As the mass and size of rice bran dust was increased, i띠ti외 smoldering temperature was l lowered. All of combustion forms were smoldering combustion. Initial smold얹ing temperature w was slightly lower with blowing condition than without blowing condition in spontaneous i ignition apparatus, which condition made heating value high.
A Study of Smoke Movement in an Enclosed Corridor.
Fire Science and Engineering, volume 13, issue 2, 1999, Pages 18~25
There are a lot of works for predicting smoke movement in a building experimentally and m numerically. It is Vel
important to predict a smoke movement in a corridor which is c connected to adjacent spaces. A numerical analysis of smoke movement in an enclosed c corridor is perlormed by a field model. The used field model is develo야d with 3-D u unstructured meshes, PISO Algorithm and buoyant plume model. In this study, tern야~ature a and flow field, some important p하ameters such as smoke spread time, hot layer temperature, c ceiling jet velocity were compared with experimental data which were perlormed in Korea I Ins디tute of Machinery and Materials. And average velocity of ceiling jet by this study is c compared with Hinkley's formula. This paper shows a flow characteristic around the soffit a and average velocity of ceiling jet is i따luenced by geometry of corridor, heat output, and d distance from the fire source.
Study on Explosion Behavior of Air-born Rice Bran Dusts according to Ignition Energy
Fire Science and Engineering, volume 13, issue 2, 1999, Pages 26~32
We had investigated combustion pro야
ies of rice bran dusts. Decomposition of rice bran d dusts with temperature were investigated using DSC and the weight loss according to t temperature using TGA in order to find the thermal hazard of rice bran dusts, and the p properties of dust explosion in variation of their dust with the same particle size. Using H Hartman's dust explosion apparatus which estimate dust explosion by electric ignition after m making dust disperse by compressed air, dust explosion experiments have been conducted by v varying concen
ation and size of rice br뻐 dust. According to the results for thermodynamic stability of rice bran dust, there are little change of initiation temperature of heat generation 때d heating value for used particle size. But i initiation temperature of heat generation decreased with high heating rate whereas d decomposition heat increased with particle size. Also, the explosion pressure was increased as t the ignition energy increased and average maximum explosion pressure was 13.5 kgv'cnt for 5 BJ/60 mesh and 1.5 뼈Ie미 dust concentration.
