1. Reaction to fire performance of wood and other building products
Abstract : The theme of this thesis is the reaction to fire performanceof wood and other building products, andparticularly thematerial fire properties time to ignition, rate of heat releaseand smoke production. These properties have been measured by asmall-scale fire test method, the Cone Calorimeter, andpresented for different types of building products. READ MORE

2. Numerical Modeling of Turbulent Combustion and Flame Spread
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.

3. Functional role of fire-derived charcoal in boreal forest ecosystem processes
Abstract : Charcoal is a natural product of wildfires which operate as a major natural disturbance in boreal forested ecosystems. This carbon (C)-rich material is present in most forest soils but its effects on ecosystem processes remain poorly understood. READ MORE

4. Conversion of biomass and waste using highly preheated agents for materials and energy recovery
Abstract : One of the greatest challenges of human today is to provide the continuous and sustainable energy supply to the worldwide society. This shall be done while minimizing all the negative consequences of the operation(s) to the environment and its living habitants including human beings, taking from the whole life cycle perspective.

5. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy
Abstract : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. READ MORE
