Influence of the Injector Head Geometry on the Particle Injection in Plasma Spraying
Journal of Thermal Spray Technology, 2020In plasma spraying, the particle velocity at the injector outlet has significant influence on the particles’ penetration into the plasma jet. The geometry of the injector and the flow rate of the carrier gas determine the particle velocities. Based on numerical simulations, it is evident that higher particle velocities and thus, a deeper penetration of

Numerical Simulation of Multi Injector Cylinder Head Engine Concept Enhancing Fuel Atomization
SAE Technical Paper Series, 2021<div class="section abstract"><div class="htmlview paragraph">The insufficient level of atomization of the fuel drops in direct-injection engines is a major cause of pollutant emissions because of the incomplete combustion process. The fuel injection is a critical part of the homogeneous air-fuel mixture.

Failure Analysis of a MEMS Micro-Injector Printing Head
2007 14th International Symposium on the Physical and Failure Analysis of Integrated Circuits, 2007The failure mechanism of a monolithic MEMS twin-bubble micro-injector failed to eject ink smoothly has been investigated. A model that analyzes the thermal expansion mismatch among the nozzle plate, the silicon substrate, and the PPO housing is proposed to explain the failure mechanism of the MEMS micro-injector printing head.
