Three-dimensional Numerical Analysis of Flow inside an Automotive Air Filter 2006-01-2629
The proposed paper aims to present the three-dimensional CFD analysis of flow inside an automotive air filter conducted by SMARTtech Fluidos for SOGEFI Filtration do Brasil Ltda., in order to determine the pressure drop over an AIS (Air Intake System). Two geometries have been analyzed in seven operation conditions, each. The flow was considered steady-state, incompressible, turbulent and isothermal. The region occupied by the filter element was treated as a porous medium and the porosity coefficients were extracted from experimental results. The contribution given by each component to the total pressure drop was determined.
