Abstract
The present work studies the compressible flow of an ideal gas in a convergent-divergent nozzle of a 200 N thrust rocket engine to determine the flow proprieties and its characteristics. The work focuses on a numeric study making use of the Finite Volume Method to approximate the Navier-Stokes equations. Among the used tools, Gmsh stands out for the geometric model reproduction and the nozzle’s hexagonal mesh formulation. For the modelling of the problem, and solution of it, the OpenFoam was used. Three situations were studied: subsonic flow regime, supersonic with the presence of normal shock waves and the design point condition.
