Abstract
This work presents a comparison between the numerical and experimental results of the analyses of two different types of radial rotors used in an agricultural fertilization system at a rotation equal to 4000 rpm. To validate the numerical analysis, experiments were carried out on a test bench using a hot-wire anemometer for speed measurements and a Pitot tube for the pressure sockets according to the standard for laboratory tests. The turbulent mean field was obtained with the Reynolds Averaged Navier Stokes (RANS) and the turbulence model used to close the set of equations was the k-Epsilon model of two equations. The computational fluid dynamics code CFX 18.1 was used to obtain the solutions of the transport equations, which uses the Finite Volume technique as a numerical method. In all models, we used non-structured tetrahedral meshes generated by the commercial software ICEM CFD 18.1. The main results showed that the methodology employed is adequate and able to reproduce the fluid dynamics behavior of the air flow.
