The design of air ducts of an Automotive Ventilation System presents as one of the complicators the restriction of space. In its design a symmetrical configuration is not always possible, due to the presence of anothers components of the vehicle, thus the ducts are distributed in asymmetric structures and normally have sharp curves, configurations that contribute to the loss, irregular distribution of the flow and production of noise. This work presents a numerical study of the incompressible flow of air in the ducts of an automotive ventilation system. The purpose is to study and compare the behavior of the fluid dynamic flow, the loss on the process and the flow distribution between two different ducts: one with symmetrical geometry and the other one with asymmetrical geometry. The study was performed using commercial software Star CCM +® that employs finite volume method.
