Validation of two embedded computational fluid dynamics formulations in kratos multiphysics

Abstract

The main advantage of embedded formulations in front of body-fitted ones is to get rid of the ALE mesh problem and its complexities. Besides, they suppress the model clean up tasks, since the problem is not solved for the real geometry but for a distance function that represents it. In this context, two different embedded formulations have been developed in Kratos Multiphysics. The first one is suitable for bodies with well defined internal volume (e.g. airfoils) while the second one is intended to be used in bodies with no internal volume (e.g. boat sails).
