The mathematical part covers the implementation and comparison of different numerical schemes to solve the equations of radiation hydrodynamics. One and the same two-dimensional model of solar granulation is simulated with different high resolution numerical methods (essentially non-oscillatory and convex non-oscillatory) and non-grey short characteristic radiative transfer. Furthermore the influence of artificial diffusivities is studied. The second part covers two astrophysical applications. A two-dimensional non-grey high resolution simulation of a downflowing plume in the sun and a grey three-dimensional simulation of the quiet sun are presented.…mehr

Produktbeschreibung
The mathematical part covers the implementation and
comparison of different numerical schemes to solve
the equations of radiation hydrodynamics. One and the
same two-dimensional model of solar granulation is
simulated with different high resolution numerical
methods (essentially non-oscillatory and convex
non-oscillatory) and non-grey short characteristic
radiative transfer. Furthermore the influence of
artificial diffusivities is studied. The second part
covers two astrophysical applications. A
two-dimensional non-grey high resolution simulation
of a downflowing plume in the sun and a grey
three-dimensional simulation of the quiet sun are
presented.
