  2. 1. Numerical Study of Cellular Instability in Burner Stabilized Adiabatic Laminar Premixed Flames

    Author : Jiangfei Yu; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Detailed Numerical Simulation; Cellular premixed flame; Hydrogen; Oxy-fuel; Heat-flux burner; Hydrodynamic instability; Diffusive-thermal instability; Nonlinear flame dynamics.;

    Abstract : The thesis deals with experiments and numerical simulations of adiabatic laminar premixed flames anchored to a heat-flux burner using different mixtures under various operating conditions. The aim is to obtain a better understanding of cellular instability in heat-flux burner anchored flames. READ MORE

  4. 2. Upgrading Cellulose Networks: Conquering Limitations in Fiber Foams

    Author : Eliott Jean Quentin Orzan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross-linking; pore structure; cellular solid; lightweight; porous network; cellulose; flame-retardancy; fibers;

    Abstract : The battle to create structural materials with low environmental impact demands the investiture of two champions: porous structures and cellulose substrates. The dominant solutions when constructing strong lightweight materials are plastic and metallic foams, while currently, cellulose fiber foams suffer from challenges which hamper their development.
