CFD assessment of a steady and pulsed jet in a catalytic converter with a 2D mesh and a 3D mesh

Escartí Guillem, Mara Salut (Universitat Politècnica de València, 2020-05-11)

[ES] Debido al aumento de la contaminación de los automóviles, la industria automovilistica ha incluido convertidores catalíticos en sus tubos de escape. Pero el comportamiento de flujo dentro del monolito catalítico y en ...
Computational approach for the acoustic modelling of large aftertreatment devices with multimodal incident sound fields

Sánchez-Orgaz, Eva María; Denia, F. D.; Martínez Casas, José; Carballeira, Javier (SAGE Publications, 2023-09)

[EN] The influence of multimodal incident sound fields on the acoustic behaviour of large aftertreatment devices incorporating a monolith is modelled and analysed in detail. The analytical mode matching method is applied ...
Efficient finite element modelling of sound propagation in after treatment devices with arbitrary cross section

Denia Guzmán, Francisco David; Sánchez Orgaz, Eva María; Ferrándiz-Catalá, Borja; Martínez Casas, José; Baeza González, Luis Miguel (2020-07-10)

[EN] The acoustic modelling of exhaust after-treatment devices, such as catalytic converters (CC) and diesel particulate filters (DPF), usually requires the use of multidimensional numerical techniques to assess the influence ...
Estudio numérico de las capacidades predictivas del modelo de turbulencia Reynolds Averaged Navier-Stokes (RANS) aplicado a convertidores catalíticos

Sánchez Abad, Nour (Universitat Politècnica de València, 2017-02-13)
