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 ...

Experimental Tests Results of Traspiration Cooling Subscale Injector Head in the frame of LYRA Program

2019
In the frame of the LYRA Program, funded by the Italian Space Agency, the LM-10-MIRA engine has been successfully tested. The engine has a vacuum thrust of 10-tons and has been developed by a joint Avio-KBKhA propulsion team in the frame of a dedicated ASI-Roscosmos inter-agencies agreement. After the experimental test campaign, further improvement for

Development of a Research-Oriented Cylinder Head with Modular Injector Mounting and Access for Multiple In-Cylinder Diagnostics

SAE Technical Paper Series, 2017
<div class="section abstract"><div class="htmlview paragraph">Alternative fuel injection systems and advanced in-cylinder diagnostics are two important tools for engine development; however, the rapid and simultaneous achievement of these goals is often limited by the space available in the cylinder head.

“A Costly Turn On”: Patterns of use and perceived consequences of mephedrone based head shop products amongst Irish injectors

International Journal of Drug Policy, 2012
Mephedrone injecting has recently been reported in Romania, Slovenia, Guernsey and Ireland. The research reported here aimed to describe the experiences of a group of Irish injecting drug users, who were injecting mephedrone based headshop products prior to the introduction of legislative controls in Ireland, with particular focus on pre- and post ...

Effects of Coiled Tubing Injector Head Abrupt Stop on the Coiled Tubing Strings

SPE/ICoTA Well Intervention Conference and Exhibition
Abstract This paper investigates the mechanical consequences of abrupt stops of coiled-tubing (CT) injector-head movement during heavy-pipe running-in-hole (RIH) operations. The objective is to quantify the transient dynamic loads produced during abrupt deceleration events, correlate those events with field-observed longitudinal plow ...

Resolving Rigless ESP Deployment Challenges Using a Modified Coiled Tubing Injector Head

SPE Middle East Artificial Lift Conference and Exhibition
Abstract Electric Submersible Pumps (ESPs) are conventionally rig-deployed via production tubing, with clamped-on power cable. The long wait and installation times incur high operating expenses, with large surface and carbon footprints. Riglessly-deployed, permanent ESP systems address the above limitations, but challenges include safe ...

Acid Stimulation in Water Injector: Managing Formation Clogging Under Sustained High Tubing Head Pressure

SPE/ICoTA Symposium and Exhibition - Well Intervention
Abstract This study aims to evaluate the causes of reduced injectivity in a water injection well following an acid stimulation operation. The scope includes analyzing pre-stimulation performance, identifying formation damage root cause, and deriving lesson(s) learned to improve future acid stimulation designs for water injectors ...
