    Abstract : This thesis aims to provide insight into three important aspects of modern computer simulation techniques related to advanced photonic semiconductor devices. These aspects are quantum size effects, waveguiding properties, and device dynamics. READ MORE

  5. 8. Analysis of Acoustic Absorption with Extended Liner Reaction and Grazing Flow

    Author : Anna Färm; Mats Åbom; Lars Enghardt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; acoustic lining; non-locally reacting; boundary layer; grazing flow; sound field; transfer matrix method;

    Abstract : Acoustic absorbing liners are efficient and commonly used measures to reduce sound levels in many fields of application. The sound reducingperformance of the liners is dependent on the acoustic state, defined by e.g. the flow and sound field interacting with the liner. READ MORE

  6. 9. Transport Coefficients during Drying of Solids containing Multicomponent Mixtures

    Author : Rafael Gamero; Joaquín Martínez; Evangelos Tsotsas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capillary; conduction; convection; diffusion; evaporation; heat transfer; hydraulic conductivity; liquid film; liquid transport; mass transfer; Maxwell-Stefan diffusion coefficients; molar fluxes; phase equilibrium; temperature gradient; ternary mixture; thermodynamic factors; Chemical engineering; Kemiteknik;

    Abstract : This study investigated the transport coefficients involved in mass and heat transfer during the drying of a porous solid partially saturated with multicomponent mixtures.  It included the coefficients governing liquid transport through the solid, the matrix of multicomponent diffusion coefficients in the liquid phase, and the effective thermal conductivity.
