No online documentation is provided, but a detailed manual comes with the distribution and can be viewed graphically or printed out. The main package is not freeware, but they do have a smaller version entitled EQS4WIN Lite which is available for free dowwnload. Online documentation is provided for both. The solver has been applied to models as large as 120,000 elementary reactions, and can be readily via a spreadsheet mechanism which eliminates the need for users to code in reactions by hand. The code is available for free download, and appears to function on most UNIX systems.
Documentation is provided with the distribution file.
A stochastic particle method is used to calculate evaporating liquid sprays, including the effects of droplet collisions and aerodynamic breakups. Chemical reactions are allowed, with a built-in focus on internal combustion engine calculations, but a flexible modularity permitting application to numerous reactive hydrodynamic problems. The method is based on variational transition state theory augmented by several multidimensional semiclassical tunneling approximations. The code is available on a variety of UNIX platforms, MacIntosh and Windows, and couples conveniently to the Gaussian 98 program. The code is available for free, but one must register first to obtain a download password.
