Analysis of spray/wall impingement using an ECN single-hole injector and a controlled-temperature wall under realistic engine conditions

Peraza, Jesús E; Payri, Raul; Gimeno, Jaime; Carvallo-Garcia, Cesar (Elsevier, 2022-05-25)

[EN] Spray¿wall interactions (SWI) directly affect fuel¿air mixture and emissions formation. Therefore, they are considered among the most critical physical processes in engine research nowadays. However, the physics of ...
ECN Spray D visualization of the spray interaction with a transparent wall under engine-like conditions, Part II: Impinging spray combustion

Peraza, Jesús E; Payri, Raul; Gimeno, Jaime; Marti-Aldaravi, Pedro (Elsevier, 2022-01-15)

[EN] In spite of the ever more comprehensive studies on diesel combustion, there is still an important gap on the fundamental knowledge about the interaction of fuel sprays with the piston and cylinder walls in internal ...
ECN Spray D visualization of the spray interaction with a transparent wall under engine-like conditions. Part I: Non-reactive impinging spray

Peraza, Jesús E.; Salvador, Francisco Javier; Gimeno, Jaime; Ruiz-Rosales, Santiago (Elsevier, 2022-01-01)

[EN] The possibility for a jet of fuel to collide against the surfaces of the combustion chamber or the piston bowl into a thermal engine, has a direct effect on the droplets breakup and the spray atomization. In order to ...
Effect of the nozzle holder on injected fuel temperature for experimental test rigs and its influence on diesel sprays

Gimeno, Jaime; Marti-Aldaravi, Pedro; Carreres, Marcos; Peraza, Jesús E (SAGE Publications, 2018)

[EN] One of the test boundary conditions whose control is necessary for both experimental and numerical studies about the automotive engines research field is the temperature of the fuel inside the injector body during the ...
Experimental study of the diesel spray behavior during the jet-wall interaction at high pressure and high temperature conditions

Peraza Ávila, Jesús Enrique (Universitat Politècnica de València, 2020-09-02)

[EN] The potential of diesel engines in terms of robustness, efficiency and energy density has made them widely used as power generators and propulsion systems. Specifically, fuel atomization, vaporization and air-fuel ...
Experimental study of the injection conditions influence over n-dodecane and diesel sprays with two ECN single-hole nozzles. Part I: Inert atmosphere

Gimeno, Jaime; Bracho Leon, Gabriela; Marti-Aldaravi, Pedro; Peraza, Jesús E (Elsevier, 2016-10-15)

In this research, two Engine Combustion Network (ECN) mono-orifice nozzles, referred to as Spray C and Spray D. respectively, were analyzed by performing visualization tests through Schlieren and Diffused Backlight ...
Experimental study of the injection conditions influence over n-dodecane and diesel sprays with two ECN single-hole nozzles. Part II: Reactive atmosphere

Payri, Raul; Salvador Rubio, Francisco Javier; Gimeno, Jaime; Peraza, Jesús E (Elsevier, 2016-10-15)

The second part of this experimental analysis, presented in this paper, seeks to go deep on the characterization of the Spray C and Spray D nozzles from the Engine Combustion Network, investigating the penetration of fuel ...
