GUAMAN, Edwin R.; LLANES-CEDENO, Edilberto A.; CELI-ORTEGA, Santiago F.  e  ROCHA-HOYOS, Juan C.. Parameters of an Exhaust Manifold for its Computational Design. A Review. Inf. tecnol. [online]. 2019, vol.30, n.6, pp.255-268. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642019000600255.

The objective of this article was to analyze the working variables of an exhaust manifold, from a review of the different techniques applied to modeling and validation, to determine the essential parameters in the operation of the exhaust manifold. The defined process was applied based on methods, design variables, performance and the current trend in computational fluid dynamics. The utility of the model was evaluated for the application of optimization based on the objective component, thermal calculations, boundary conditions, materials for structural analysis and fatigue, in an integral manner. Therefore, a tubular design has better characteristics of gas evacuation compared to conventional collectors. This works represents a contribution for improving the performance of the vehicle. Additionally, a proposal for the rapid and efficient design of the multiple exhaust was generated.

Palavras-chave : simulation method; computational fluid dynamics; exhaust manifolds; parameter model; structural analysis.
