A fluid dynamic model for unsteady compressible flow in wall-flow diesel particulate filters

Torregrosa Huguet, Antonio José; Serrano Cruz, José Ramón; Arnau Martínez, Francisco José; Piqueras Cabrera, Pedro (Elsevier, 2011-01)

The use of particulate filters (DPF) in Diesel engines has become in recent years the standard technology for the control of soot aerosol emissions. Once emissions reduction through the management of filtration and ...
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 ...
Derivation of the method of characteristics for the fluid dynamic solution of flow advection along porous wall channels

Desantes Fernández, José Mª; Serrano Cruz, José Ramón; Arnau Martínez, Francisco José; Piqueras Cabrera, Pedro (Elsevier, 2012-07)

This paper describes in detail a novel formulation of the method of characteristics for its application to solve one-dimensional compressible unsteady non-homentropic flow advected along porous wall channels. In particular, ...
Diseño mediante cálculo CFD de un separador ciclónico para una instalación de simulación de altitud

Rodenas Tornero, José Miguel (Universitat Politècnica de València, 2021-12-20)

Experimental theoretical methodology for determination of inertial pressure drop distribution and pore structure properties in wall-flow diesel particulate filters (DPFs)

Payri González, Francisco; Broatch Jacobi, Jaime Alberto; Serrano Cruz, José Ramón; Piqueras Cabrera, Pedro (Elsevier, 2011-12)

Wall-flow particulate filters have been placed as a standard technology for Diesel engines because of the increasing restrictions to soot emissions. The inclusion of this system within the exhaust line requires the development ...
Filtration modelling in wall-flow particulate filters of low soot penetration thickness

Serrano Cruz, José Ramón; Climent, H.; Piqueras, P.; Angiolini, Emanuele (Elsevier, 2016-10-01)

A filtration model for wall-flow particulate filters based on the theory of packed beds of spherical particles is presented to diagnose the combined response of filtration efficiency and pressure drop from a reliable ...
Fuel economy benefits in internal combustion engines due to soot restructuring in the particulate filter by water injection

Serrano, J.R.; Piqueras, P.; Angiolini, Emanuele; Garcia-Afonso, Oscar (SAGE Publications, 2023-04)

[EN] Wall-flow particulate filters are key elements to control particulate matter emissions. The stricter emission standards also for non-road mobility machinery makes this device essential to improve the air quality in ...
Impact of Employing Hybrid Nanofluids as Heat Carrier Fluid on the Thermal Performance of a Borehole Heat Exchanger

Javadi, Hossein; Urchueguía Schölzel, Javier Fermín; Ajarostaghi, Seyed Soheil Mousavi; Badenes Badenes, Borja (MDPI AG, 2021-05)

[EN] In this numerical study, 4 types of hybrid nanofluid, including Ag-MgO/water, TiO2-Cu/water, Al2O3-CuO/water, and Fe3O4-multi-wall carbon nanotube/water, have been considered potential working fluid in a single U-tube ...
