Resumen:
It is well known that openFoam has become a very popular tool for research work in different fieldsand particularly, in fluid dynamics. But, it is also known its lack of detailed documentation support-ing solvers made using the set of libraries provided by openFoam. Therefore, it becomes necessary toestablish appropriate verifications that can be useful to users going for instance, through the selectionof equations discretization schemes from fvSchemes libraries and of solution solvers from fvSolutionslibraries, to be later applied in the simulation of a given specific problem. With this purpose, executablesolvers available in openFoam 1.7 version to solve supersonic air flow problems are tested. Two differentapproaches have been taken in developing numerical methods to solve problems in transport phenomenaat all Mach numbers and traditionally, they have been referred to as pressure-based and density-basedmethods. In this work, the advantages or disadvantages in applying any one of these methods, are ad-dressed. To accomplish the proposed tasks, 2D and axisymmetric numerical simulations of well posedproblems that have either an analytical solution or available experimental data to compare with, areperformed.
