6. Extension of OpenFOAM Library for RANS Simulation of Premixed Turbulent Combustion
Sammanfattning : Unsteady multi-dimensional numerical simulation of turbulent flames is a well recognized tool for research and development of future internal combustion engines capable for satisfying stringent requirements for ultra-low emission and highly efficient energy conversion. To attain success, such simulations need, in particular, well elaborated Computational Fluid Dynamics (CFD) software, as well as advanced predictive models of turbulent burning. LÄS MER
7. Large Eddy Simulation of Turbulent Swirling Flows and Turbulent Premixed Combustion
Sammanfattning : With the increasing concerns about our environment and human health, more and more stringent emission limits have been specified. These adopted and still coming emission limits require and promote more accurate, less experiential methods to design and develop the combustors. LÄS MER
8. A Level-set Flamelet Library Model for Premixed Turbulent Combustion
Sammanfattning : The modelling of premixed turbulent combustion has been studied. Premixed turbulent combustion occurs in a range of applications, such as gas turbines and spark-ignition engines. LÄS MER
9. 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.

10. Detailed Soot Modelling in Laminar and Turbulent Reacting Flows
Sammanfattning : In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. LÄS MER
