Radiative energy loss andv2spectra for viscous hydrodynamics

Radiative Energy Loss by Galactic Cosmic Rays

Interactions between galactic cosmic rays and matter are a primary focus of the NASA radiation problem. The electromagnetic forces involved are for the most part well documented. Building on previous research, this study investigated the relative importance of the weak forces that occur when a cosmic ray impinges on di!erent types of materials. For the familiar electromagnetic case, it is known...

Improved Finite-Volume Method for Radiative Hydrodynamics

Improved Finite-Volume Method for Radiative Hydrodynamics Alan Wray* Corresponding author: [email protected] * NASA Ames Research Center, USA Abstract: Fully coupled simulations of hydrodynamics and radiative transfer are essential to a number of fields ranging from astrophysics to engineering applications. Of particular interest in this work are hypersonic atmospheric entries and associate...

Shock profiles in radiative hydrodynamics

There exists a huge variety of models intended to describe, with more or less accuracy, radiative transfer phenomena. Of course these models are more or less complex, and retain more or less details of the physics. The choice of a model among the list is definitely application-dependent, driven by the leading phenomena in the considered situation, thus depending on the values of the physical pa...

Dispersive hydrodynamics in viscous fluid conduits.

The evolution of the interface separating a conduit of light, viscous fluid rising buoyantly through a heavy, more viscous, exterior fluid at small Reynolds numbers is governed by the interplay between nonlinearity and dispersion. Previous authors have proposed an approximate model equation based on physical arguments, but a precise theoretical treatment for this two-fluid system with a free bo...
