Abstract
This works purpose is to study the air flow inside of a lateral duct of an industrial term-shrinking tunnel using computational fluid dynamics (CFD). The results showed a formation of recirculation zones, contraction and expansion occurs along the flow, as a function of fluid trajectory change. The definition of points to fluid trajectory analysis influences the result due to the distance between the points. The velocity gradient is a function of the chosen mesh. The mesh refinement increase tends to approximate the model to experimental data, however, very refined meshes tend to cause higher oscillations in the model. These results allow to conclude that the model obtained in CFD can be used to represent the real flow, supporting future studies to optimize the equipment operating conditions.
