Hydrodynamics | A visualization tool of 2D shocks simulations
https://2dshocks.wordpress.com/hydrodynamics
A visualization tool of 2D shocks simulations. An interactive module by Fernando Becerra. Euler equations describe a smooth flow. The equations represent conservation of mass (continuity equation), momentum and energy in the fluid. The set of equations are given by:. Is the total energy density. So far we have three equations and four variables, so we need a forth equation. In the case of a compressible fluid we add an equation of state (EOS) of the type. Which is equivalent to consider constant density).

2013 topical modules | ISM and Star Formation
https://ay201b.wordpress.com/topical-modules/2013-topical-modules
ISM and Star Formation. 8220;The Book”. These modules were produced by the AY 201b students of the Spring 2013 term. For a full description of the module creation process, motivations, and outcomes, see our article arXiv:1308.1908. For a summary of all the modules created in 2013, download the handout. From our May 21st event. Visualizing the Milky Way Project. Visualizing Turbulence in the ISM. Shocks in the ISM–From Simulations to Observations: This module plays with making mock observations of S...

Landmarks of the ISM. A tour of some of the most beautiful objects in the interstellar medium and an introduction to what observations at different wavelengths can tell us about them. Skip to primary content. An Overview of the ISM. An Overview of the ISM. What exactly is the interstellar medium (ISM)? In our galaxy that is between the stars. Draine divides all of this ‘stuff’ into seven components:. Or, in more technical terms, small solid particles mixed in with the interstellar gas. To learn even more...

Shocks | A visualization tool of 2D shocks simulations
https://2dshocks.wordpress.com/shocks
A visualization tool of 2D shocks simulations. An interactive module by Fernando Becerra. Shocks by definition are discontinuities in the fluid properties (e.g. density, velocity, pressure). A schematic image is shown in Fig.1, where we can clearly identify the discontinuity as a “shock jump”. The values of the fluid properties change abruptly at that interface. Pressure, energy and density have values. Respectively to the left of the shock, while to the right the values are. Which is basically jets eman...

Simulations | A visualization tool of 2D shocks simulations
https://2dshocks.wordpress.com/simulations
A visualization tool of 2D shocks simulations. An interactive module by Fernando Becerra. What is a numerical simulation? In astrophysics most processes can be described by a set of equations. A simple example are the equations of motion. Take a long time and we are not able to watch the whole process with telescopes. Another interesting example is the formation of the first structures in the Universe. A very famous simulation of large scale structure is the Millenium simulation. Based in an Lagrangian h...

Documentation | A visualization tool of 2D shocks simulations
https://2dshocks.wordpress.com/documentation
A visualization tool of 2D shocks simulations. An interactive module by Fernando Becerra. A zip version of the code is available here. Alternatively you can download pyro2 from its webpage. And add the file interface.py. To the pyro2/ directory. Here a list of programs you need to install before installing pyro2:. The only step needed to install pyro2 is building the fortran source. In order to do that just go to the pyro2/ folder and execute. Running a new simulation. Choose the initial conditions.

The Code | A visualization tool of 2D shocks simulations
https://2dshocks.wordpress.com/code
A visualization tool of 2D shocks simulations. An interactive module by Fernando Becerra. Pyro (from PYthon hydRO) was originally written in 2003-2004 by Michael Zingale. This version was resurrected beginning in 2012 and rewritten for numpy and brought up to date. pyro2. Is a 2D grid-based code mostly written in Python, with a few low-level routines written in Fortran. pyro2 employs a commonly used method to solve numerically the equations in grid-base codes, which is called the finite-volume method.
