2. 1. Numerical Modeling of Turbulent Combustion and Flame Spread

   Author : Zhenghua Yan; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Flame Spread; Pyrolysis; Heat Transfer; Radiation; CFD; Turbulent Combustion Modeling; Teknik;

   Abstract : Theoretical models have been developed to address several important aspects of numerical modeling of turbulent combustion and flame spread. The developed models include a pyrolysis model for charring and non-charring solid materials, a fast narrow band radiation property evaluation model (FASTNB) and a turbulence model for buoyant flow and flame.

4. 2. Computational strategies in flame-spread modelling involving wooden surfaces

   Author : Jörgen Carlsson; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flamspridning; computational methods; pyrolysis modelling; fire modelling; fire growth; flame spread; Computational Fluid Dynamics; CFD; brandtillväxt; brandmodellering; pyrolysmodellering;

   Abstract : Various approaches to flame-spread and fire-growth modelling are discussed and are evaluated using experimental results from different tests. Use of Computational Fluid Dynamics, CFD, in fire modelling is discussed and the performance of different CFD codes in wall flow modelling is analysed. READ MORE

5. 3. Mechanism of a polyolefin based effervescent flame retardant material

   Author : Anna Hermansson; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; flame retardant; Casico; effervescence; silicone elastomer; intumescent structure; calcium carbonate; polyolefin;

   Abstract : ABSTRACTFire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start and/or spread a fire. As a result of environmental and safety issues having to do with flame retardants based on halogens, much attention has lately been given to finding halogen free alternatives. READ MORE
