The intake flange is a mechanical device that restricts the amount of mass air flow to be injected into the engine cylinder, and is used in racing vehicles. In the present work, the air flow is simulated in a 2D computational domain with axial symmetry for the geometry of a convergent-divergent intake flange, in order to determine the variations of the thermodynamic parameters of the flow field. For the simulation of the flow, the ANSYS-Fluent code that uses the finite volume method was used. The governing equations were used for compressible flow: mass equation, amount of movement, energy and state; in addition, Menter’s SST   turbulence model was used. The results of the density, velocity, pressure and temperature flow field, as well as the Mach number, for six pressure ratios, show variations in thermodynamic quantities in different regions of the domain, before and after ...
