CFD Study of Needle Motion Influence on the Spray Conditions of Single-Hole Injectors

Margot, Xandra Marcelle; Hoyas Calvo, Sergio; Fajardo, Pablo; Patouna, Stavroula (Begell House, 2011)

[EN] The spray characteristics and, consequently, the success of the Diesel combustion process is strongly affected by the manner in which fuel is introduced in the combustion chamber. This work consists in studying the ...
Influence of biofuels on the internal flow in diesel injector nozzles

Salvador, F.J.; Martínez López, Jorge; Romero Bauset, José Vicente; Roselló, M.D. (Elsevier, 2011)

[EN] In this paper, the behavior of the internal nozzle flow of a standard diesel fuel has been compared against a biodiesel fuel (soybean oil) at cavitating and non-cavitating conditions, using a homogeneous equilibrium ...
Large Eddy Simulation for high pressure flows: Model extension for compressible liquids

Payri, Raul; Tormos, B.; Gimeno, Jaime; Bracho Leon, Gabriela (PERGAMON-ELSEVIER SCIENCE LTD, 2011)

[EN] The present study gives a general outline for the fluid-dynamical calculation of flows at high pressure conditions. The main idea is to present a mathematical description of high pressure processes in liquids at ...
Numerical simulation and extended validation of two-phase compressible flow in diesel injector nozzles

Salvador Rubio, Francisco Javier; Hoyas, S; Novella Rosa, Ricardo; Martínez López, Jorge (Professional Engineering Publishing, 2011)

In this paper, the ability of a computational fluid dynamics code to reproduce cavitation phenomena accurately is checked by comparing data acquired by numerical simulations against those obtained from different experiments ...
Study of the influence of the inlet boundary conditions in a LES simulation of internal flow in a diesel injector

Payri Marín, Raúl; Gimeno García, Jaime; Marti Aldaravi, Pedro; Bracho León, Gabriela Cristina (Elsevier, 2013-04)

In this paper the study of the behavior of the fuel flow through the injector nozzle using CFD tools is presented. Large Eddy Simulation will be used to model the internal flow turbulence in a Diesel fuel injector with ...
