Introduction: This web site is intended to provide UC3 collaborators/funders with instructions on obtaining the one dimensional turbulence (ODT) model and large eddy simulation (LES) model.

ODT Code: The one dimensional turbulence (ODT) model simulates turbulent flow along a one-dimensional line of sight. This ODT model was specifically developed to simulate oxy-coal combustion and gasification in a planar jet. This ODT model includes representation of the coal phase through the use of Lagrangian particle tracking and includes particle devolatilization and char oxidation reactions.

Download the ODT code.

LES Code: The large eddy simulation (LES) model simulates filter, 3D quantities (momentum, mass, scalar conservation) in a turbulent flow field. The name of this LES project is "ARCHES", and is an extension of previous DOE funding. The ARCHES code includes particle phase representation of through the use of moment methods, particularly the direct quadrature method of moments (DQMOM).

The ARCHES code is integrated into a C++ framework called Uintah, whose purpose is to provide large scale parallelization tools for physics components (such as ARCHES). The code is constantly under development by a number of people and is maintained in an svn code repository. Distribution through the repository is freely available. Periodically, release distributions of the framework along with the ARCHES component can be found on the distribution website of Uintah. Questions regarding the ARCHES code may be directed at Dr. Jeremy Thornock .

Instructions for obtaining the SVN distribution (bleeding-edge) of ARCHES/Uintah.

The latest ARCHES/Uintah release (stable release) including the latest documentation.
