This work applied the mathematical models already implemented in the OpenFOAM ® computational fluid dynamics (CFD) software, to simulate two proposed air distributions inside cold chambers. The OpenFOAM ® software was chosen because of the absence of licensing costs associated with its use, compared to the major commercial CFDsoftwares available. In the pre-processing phase, we used the free Google SketchUp ® software for the virtual design of the prototypes, and the free enGrid ® software for the discretization of these virtual prototypes; later the resulting grids were used, by the OpenFOAM ® , in the post-processing phase.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
