11. Radiative Heat Transfer in Suspension-Fired Systems
Sammanfattning : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. LÄS MER
12. Numerical Modeling of Turbulent Combustion and Flame Spread
Sammanfattning : 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.

13. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies
Sammanfattning : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. LÄS MER
14. Heat transfer phenomena and mould flux lubrication in continuous casting of steel
Sammanfattning : Overall thermal resistance of the mould flux was measured tomake clear the influence of the mould flux properties on theheat transfer behavior in continuous casting, especiallythermal conductivity and the formation of air gaps in thisstudy. From the investigation of the effect of the mouldsurface temperature and physical properties of the mould fluxon heat transfer through the flux film, following knowledge hasbeen obtained. LÄS MER
15. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces
Sammanfattning : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. LÄS MER
