Modeling deposit formation in diesel injector nozzle
Formation of deposit in the diesel injector nozzle affects the injection behavior and hinders performance. Under running condition, deposit precursors are washed away by the ensuing injection. However, during the cool down process after engine shut down, fuel, detergent chemistry, and fluid …

AN AUTOMATIC INJECTOR AND TIMING DEVICE FOR CARDIAC RESEARCH
Some of the prior techniques for taking coronary arteriograms have involved the injection of large quantities of potentially toxic radio-opaque dye directly into the root of the aorta, followed by the taking of an X-ray picture. By synchronizing the injection and the firing of the X-ray machine to …

Experimental Studies of Injector Array Configurations for Circular Scramjet Combustors
A flush-wall injector model and a strut injector model representative of state of the art scramjet engine combustion chambers were experimentally studied in a cold-flow (non-combusting) environment to determine their fuel-air mixing behavior under different operating conditions. The experiments …

Adjoint-based geometry optimisation with applications to automotive fuel injector nozzles
Methods of Computational Fluid Dynamics (CFD) have matured, over the last 30 years, to a stage where it is possible to gain substantial insight into fluid flow processes of engineering relevance. However, the motives of fluid dynamic engineers typically go well beyond the level of improved …

The dual-piston jet injector and the viability of drug delivery
… delivery systems. A two-piston system in a jet injector enables the use of a cyclic motion of pistons to drive the injected fluids, as opposed to the one-piston design that requires resetting the mechanism. This provides a way to dispense high-volume doses of medication without reloading. In …

Needle-free interstitial fluid acquisition using a Lorentz-force actuated jet injector
… ISF samples using a Lorentz-force actuated jet injector. The jet injector is used to first inject a small volume of physiological saline to breach the skin, and the actuator is subsequently back-driven to create a vacuum in the ampoule and collect a sample that contains a mixture of ISF and …

An attack model, language, and injector for the control plane of software-defined networks
… thesis introduces a model, a language, and an injector for describing and injecting attacks into the control plane of the OpenFlow-based SDN architecture. First, we define an attack model that models the components in the SDN network and the assumptions about an attacker's capabilities against …
