    Abstract : Triticum aestivum L., commonly known as bread wheat, characterized by a chromosomal composition of 2n = 6x = 42 (AABBDD), is a significant source of dietary protein and daily calorie intake for much of the global population. Stripe rust (Puccinia striiformis Westend. f. READ MORE

  4. 2. Modeling of Pulverised Wood Flames

    Author : Ashraf Elfasakhany; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; plasma; combustion; pulverised wood; two-phase flow; devolatilization; emissions; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Termisk teknik; termodynamik;

    Abstract : The aim of the current work was at development and validation of modeling tools for simulation of pulverised wood flames in furnaces and study how different factors influence on such flames. The numerical model involves different sub-models for the physo-chemical processes, such as, two-phase flow motion, drying, devolatilization and shrinkage of particles, the formation and oxidation of volatile, tar and char, turbulence-chemistry interaction, turbulence-radiation interaction, etc. READ MORE
