absolute instability
Opis:: In the present paper the instability character (absolute/convective) of compressible viscous flow around geometries rotating in uniform flow is analysed. The linear local stability theory is used to investigate the boundary layer stability. Following the works of Briggs and Bers in the field of plasma physics, the absolute instability region is identified by singularities of dispersion relation called pinch - points. Calculations have been made for different Mach numbers and wall temperatures.

Opis:: The lifetime estimation of power station structures and components, subjected to fatigue loading, is essential for determining the moment of repair or replacement. Therefore the degradation behaviour and damage development within material should be very well understood. This research focuses on a fluid-solid interaction that has been developed in Finite Volume Method software for description of heat and flow loading on a cut-off valve and Finite Element Method software for conduct researches on fatigue and creep damage of the valve material.

Tytuł:: A parallel adaptive code for compressible Navier-Stokes simulations
Autorzy:: Banaś, K.
Powiązania:: https://bibliotekanauki.pl/articles/1954541.pdf
Data publikacji:: 1999
Wydawca:: Politechnika Gdańska
Tematy:: numerical simulations
compressible flow
Navier-Stokes solver
finite element method
parallel computing
adaptive meshes
Opis:: The paper presents a finite element code for compressible flow simulations. The code has two important features: adaptivity to increase accuracy of computations by selectively refining a finite element mesh and efficient parallel performance due to a special implementation based on concept of patches of elements. The algorithm for approximating the compressible Navier-Stokes equations is a version of the stabilized finite element method. Three time integration strategies are implemented, explicit, linear implicit and nonlinear implicit, and the GMRES method is used to solve systems of linear equations. For parallel simulations the code uses a special algorithm for mesh partition. The performance of the code is tested for two examples of supersonic flows: one inviscid and one viscous.
