Abstract
Corner fires are known to spread more intensely in comparison to single wall fires. In view of the challenges associated with the prediction of such fire behavior, the fire growth in a corner configuration is investigated to provide a set of experimental data, consisting of 21 Single Burning Item (SBI) tests with Calcium Silicate (CS), Medium-Density Fiberboard (MDF) and plywood panels. The results of total Heat Release Rate (HRR), total Smoke Production Rate (SPR), puffing frequency, flame spread, flame heights, panel temperatures, and total heat fluxes at several characteristic locations are analyzed. This set of experimental data is expected to be useful for evaluation of fire simulation capabilities. In order to carefully examine the effect of the heat exchange between the two corner walls on the flame spread and fire behavior, 3 test groups are considered: (A) inert tests with two calcium silicate panels; (B) flame spread tests with one inert panel and one plywood or MDF panel; and (C) flame spread tests with two plywood or MDF panels. In addition to the experiments, a Computational Fluid Dynamics (CFD) study is conducted using FireFOAM 2.2.x, consisting of several Large Eddy Simulations (LES), allowing to evaluate the current modeling capabilities for prediction of the corner fire behavior.
Hoekbranden staan erom bekend dat ze zich intenser verspreiden in vergelijking met branden aan een enkelvoudige wand. Met het oog op de uitdagingen die gepaard gaan met het voorspellen van dergelijk brandgedrag, wordt de brandgroei in een hoekconfiguratie onderzocht om een set van experimentele gegevens te leveren, bestaande uit 21 Single Burning Item (SBI) proeven met calciumsilicaat- (CS), MDF- en multiplexpanelen. De resultaten van het totale warmtevermogen (HRR), totale rookproductiesnelheid (SPR), puffrequentie, vlamverspreiding, vlamhoogten, paneeltemperaturen en totale warmtefluxen worden geanalyseerd op verschillende karakteristieke locaties. Deze serie van experimentele gegevens zal naar verwachting nuttig zijn voor evaluaties van de mogelijkheden van brandsimulaties. Om het effect van de warmtewisseling tussen de twee hoekwanden op het brand- en vlamverspreidingsgedrag zorgvuldig te onderzoeken, worden 3 testgroepen beschouwd: (A) inerte proeven met twee calciumsilicaatpanelen; (B) vlamverspreidingsproeven met één inert paneel en één multiplex- of MDF-paneel, en (C) vlamspreidingsproeven met twee multiplex- of MDF-panelen. Naast de experimenten wordt een CFD (‘Computational Fluid Dynamics’) studie uitgevoerd met behulp van FireFOAM 2.2.x, bestaande uit verschillende Large Eddy Simulations (LES), om de huidige mogelijkheden voor modellering voor het voorspellen van het gedrag van hoekbrand te evalueren.
