A study of the early life of Gasoline Particulate Filters: reactive and dissipative acoustic effects

Torregrosa, A. J.; De La Morena, Joaquín; Sanchis Pacheco, Enrique José; Redondo-Navarro, Álvaro Rafael; Servetto, Emanuele (SAGE Publications, 2022-10)

[EN] The presence of after-treatment systems (ATS) has some side effects as they modify the wave dynamics, back-pressure and acoustic behavior of the exhaust system, that define the boundary conditions for the main silencing ...
Acoustic and Fluid-Dynamic Characterization of State-of-the-Art Exhaust After-Treatment Systems

Redondo Navarro, Álvaro Rafael (Universitat Politècnica de València, 2023-06-26)

[ES] Las normativas sobre emisiones contaminantes y sonoras, cada vez más estrictas, han sido la principal motivación para la investigación, el desarrollo y la optimización de los motores de combustión y demás tecnologías ...
Assessment of the fluid-dynamic and acoustic behaviour of a swirl static mixer for after-treatment systems

Torregrosa, A. J.; Broatch, A.; Quintero-Igeño, Pedro-Manuel; Redondo-Navarro, Álvaro Rafael; Morin, F. (Elsevier, 2022-01-15)

[EN] An investigation on the acoustic transmission loss and the pressure drop caused by a mixer inducing element located downstream of a Diesel Exhaust Fluid (DEF) injection port was carried out in order to reduce the ...
Experimental Characterization and Improved Modelling Methodology for Simple Geometry After-treatment Devices Focused on Pressure Drop and Transmission Loss

Redondo Navarro, Álvaro Rafael (Universitat Politècnica de València, 2021-01-13)

[ES] Los modelos computacionales tienen potencial para ser empleados como estimadores del desempeño de nuevos dispositivos de postratamiento en varios aspectos, tales como la caída de presión y la perdida por transmisión, ...
On the applicability of cold acoustic measurements to high-amplitude hot pulsating flows

Torregrosa, A. J.; Piqueras, P.; Sanchis Pacheco, Enrique José; Redondo-Navarro, Álvaro Rafael (Springer-Verlag, 2023-03)

[EN] The experimental characterization of the acoustic characteristics of engine exhaust devices is usually carried out through measurements in cold conditions, due to the intrinsic difficulties associated with proper ...
