Análisis de flujo de aire en el conducto de admisión y válvula de admisión de una motocicleta suzuki de 125cc mediante dinámica de fluidos computacional.

Abstract

The present Project aims to analyze the flow air in the duct and the intake valve in an Otto cycle engine of a Suzuki motorcycle, 125cc, through Finite Element Method using the Ansys Worckbench computing platform. The analysis was carried out by taking physical steps of the current model, corresponding to the cylinder head and intake valve for subsequent 3D modeling in the SolidWorks platform, defining the internal geometries to extract the geometries of flow, that is, where the air-fuel mixture is conveyed, until to reach the combustion chamber to become energy. The parameters where established with the meshing of the fluid geometry, defining the type of mesh the three – dimensional elements used to resolve the flow of the air-fuel mixture. The boundary conditions were also analyzed, that is, input facets and output pressurized of atmospherics air were defined; sections that represents the inside of the fluid, and boundary surfaces that are the limit of the fluid or wall, by explaining step by step the performed development for simulation. The flow analysis took certain initial conditions of the air like: Pressure reference (atmospheric), temperature of absolute reference (K), pre-mixed of gasoline in the air (by default), without taking into account the energy dissipation, heat transfer, radiation, etc. A theoretical comparison was performed with the obtained results from the simulation as: Velocity gas within geometry, air consumption and turbulence with the obtained data of the cited bibliographies at work.
