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 ...
Energy extraction from a pitching-plunging airfoil

García Lucas, Manuel (Universitat Politècnica de València, 2022-09-28)

[EN] The energy extraction capabilities of an airfoil performing oscillatory pitching and plunging motions in turbulent conditions are studied by means of two-dimensional, unsteady CFD simulations. A parametric study in ...
Heat transfer modeling in exhaust systems of high-performance two-stroke engines

Lujan Martinez, José Manuel; Climent Puchades, Héctor; Olmeda González, Pablo Cesar; Jiménez Macedo, Víctor Daniel (Elsevier, 2014-08)

Heat transfer from the hot gases to the wall in exhaust systems of high-performance two-stroke engines is underestimated using steady state with fully developed flow empirical correlations. This fact is detected when ...
Heat transfer modelling in honeycomb wall-flow diesel particulate filters

Galindo, José; Serrano Cruz, José Ramón; Piqueras, P.; García Afonso, Óscar (Elsevier, 2012-07)

Heat transfer in wall-flow monoliths has gained in interest because of the widespread adoption of these systems by automotive industry to fulfil soot emission regulations and the importance of heat exchange on the regeneration ...
Numerical modeling of cavitating flows for simple geometries using FLUENT V6.1

Palau-Salvador, Guillermo; González Altozano, Pablo; Arviza Valverde, Jaime (Instituto Nacional de Investigacion y Tecnologia Agraria y Alimentaria, 2007-12-01)

[EN] Cavitation is a phenomenon that can be present in several agro-forestry applications such as irrigation pressure-reducing valves, sprinkler orifices or even in the flow through xylem vessels inside plants. In the ...
PATs Operating in Water Networks under Unsteady Flow Conditions: Control Valve Manoeuvre and Overspeed Effect

Pérez-Sánchez, Modesto; López Jiménez, Petra Amparo; Ramos, Helena M. (MDPI AG, 2018-04)

[EN] The knowledge of transient conditions in water pressurized networks equipped with pump as turbines (PATs) is of the utmost importance and necessary for the design and correct implementation of these new renewable ...
