  2. 1. Spontaneous and stimulated X-ray Raman scattering

    Author : Yu-Ping Sun; Faris Gel'mukhanov; Vincenzo Carravetta; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant X-ray scattering; resonant Auger scattering; rotational Doppler broadening; XFEL pulse; Atomic and molecular physics; Atom- och molekylfysik; Spectroscopy; Spektroskopi;

    Abstract : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. READ MORE

  4. 2. Analytical vortex solutions to Navier-Stokes equation

    Author : Henrik Tryggeson; Mats Lyberg; Maarten Brons; Växjö universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conical vortex; Navier-Stokes equation; analytical solution; 2-D vortices; turbulence; vortex ring; stretched vortex; coherent structures; Fluid mechanics; Strömningsmekanik;

    Abstract : Fluid dynamics considers the physics of liquids and gases. This is a branch of classical physics and is totally based on Newton's laws of motion. Nevertheless, the equation of fluid motion, Navier-Stokes equation, becomes very complicated to solve even for very simple configurations. READ MORE

  6. 4. An Analytical Solution Applied to Heat and Mass Transfer in a Vibrated Fluidised Bed Dryer

    Author : Apolinar Picado; Joaquín Martínez; Göran Lindbergh; Ivars Neretnieks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical solution; Heat and mass transfer; Temperature and moisture distribution; Drying modelling; Multicomponent drying; Drying selectivity; Volatile retention; Ternary mixture; Drying of particulate materials; Vibrated fluidised bed dryer; Chemical engineering; Kemiteknik;

    Abstract : A mathematical model for the drying of particulate solids in a continuous vibrated fluidised bed dryer was developed and applied to the drying of grain wetted with a single liquid and porous particles containing multicomponent liquid mixtures. Simple equipment and material models were applied to describe the process. READ MORE

  7. 5. Some numerical and analytical methods for equations of wave propagation and kinetic theory
