    Author : Mikhail Modestov; Vitaly Bychkov; Mattias Marklund; Tito Mendonca; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; front; instability; deflagration; fysik; Physics;

    Abstract : The concept of a front plays a decisive role in various elds in physics and beyond. In the present thesis we study key aspects of front dynamics and stability in the context of laser plasmas, organic semiconductors and quantum media. READ MORE

  4. 2. Numerical Simulations of Physical Discontinuities in Single and Multi-Fluid Flows for Arbitrary Mach Numbers

    Author : Gang Zhou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Physical discontinuities, such as shocks and interfaces occur commonly in fluid mechanics. The emphasis of this dissertation lies on numerical simulations of shocked aerodynamic flows and two fluid flows with sharp interfaces in which Rayleigh-Taylor instability is present. READ MORE

  5. 3. Turbulent burning, flame acceleration, explosion triggering

    Author : V'yacheslav Akkerman; Vitaly Bychkov; Geoffrey Searby; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Turbulent combustion; flame acceleration; detonation explosion triggering; direct numerical simulations; Physics; Fysik;

    Abstract : The present thesis considers several important problems of combustion theory, which are closely related to each other: turbulent burning, flame interaction with walls in different geometries, flame acceleration and detonation triggering. The theory of turbulent burning is developed within the renormalization approach. READ MORE

    Author : Dmitry Kobyakov; Emil Lundh; Vitaly Bychkov; Mattias Marklund; Achim Schwenk; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Binary Bose-Einstein condensates in ultracold gases; hydrodynamics; quantum turbulence; neutron stars; the inner crust; nuclear astrophysics; fysik; Physics;

    Abstract : In the present thesis, “Hydrodynamics of Binary Bose-Einstein Condensates and Hydro-elasticity of the Inner Crust of Neutron Stars”, the hydrodynamic effects, instabilities and superfluid turbulence in binary immiscible ultracold gases, and hydro-elastic macroscopic coupled modes and microscopic structure of the inner layers of the crust of neutron stars, are studied. The ultracold gas dynamics can be realized in the laboratory. READ MORE

  7. 5. An Immersed Finite Element Method and its Application to Multiphase Problems

    Author : Alexei Loubenets; Björn Engquist; Michael Shelley; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluid and plasma physics; applied mechanics; computer science; Numerical analysis; Numerisk analys;

    Abstract : Multiphase flows are frequently encountered in many important physical and industrial applications. These flows are usually characterized by very complicated structure that involves free moving surfaces inside the fluid domain and discontinuous or even singular material properties of the flow.
