Influence of Injector Head Geometry on Particle Injection in Plasma Spraying

International Thermal Spray Conference, 2019
Abstract This study assesses the effect of injector geometry on particle injection in plasma spraying. Numerical simulations show that high particle velocities can be realized with an injector that is significantly longer than the norm. In order to verify the prediction, injectors with different diameters and lengths were used to spray ...

Experimental Collision and Swirl of CFD Simulated Fuel Sprays in a Dual Injector Cylinder Head Concept

SAE Technical Paper Series, 2023
<div class="section abstract"><div class="htmlview paragraph">A higher level of atomization of the fuel leads to a more homogeneous mixture with the air in internal combustion engines, whether they are equipped with direct injection or port fuel injected systems. The further break-up of the atomized fuel drops by the interaction of two fuel

Study on Mechanism of Coiled Tubing Surface Damage in Injector Head

SPE/ICoTA Well Intervention Conference and Exhibition, 2019
Abstract According to literature, most failures of coiled tubing are classified into four kinds of causes, mechanical damage, corrosion, string manufacturing, and human error. Among these, the failures due to mechanical damages take 29% of all failures.

Optimization of Injector Location on the Cylinder Head in a Direct Injection Spark Ignition Engine

2020
The injector location and orientation on the cylinder head of a direct injection spark ignition engine greatly influence the performance, combustion, and emission characteristics. As the cylinder head is the most crowded area, an in-cylinder investigation needs to be performed for the optimization of the spark plug and injector location. In this study,

Analysis of hydro-abrasive erosion in a high-head Pelton turbine injector using a Eulerian-Lagrangian approach

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2023
High-head hydropower plants deploy Pelton turbines to harness energy; however, turbine components face severe abrasive erosion due to suspended sediments. The erosion of the Pelton injector leads to the degradation of the jet quality, reducing the turbine efficiency considerably.

Injector Head Transpiration Cooling Coupled with Combustion in H2/O2 Subscale Thrust Chamber

Journal of Thermophysics and Heat Transfer, 2013
Transpiration cooling coupled with combustion was investigated in an H2/O2 liquid rocket thrust chamber with a transpiration-cooled injector plate. A numerical model was developed using the real gas equation of state. The H2 and O2 combustion process was modeled by the eddy dissipation concept model, which includes the detailed chemical reaction ...
