Fault Reactivation by Fluid Injection: Controls From Stress State and Injection Rate [PDF]

open access: yesGeophysical Research Letters, 2018
We studied the influence of stress state and fluid injection rate on the reactivation of faults. We conducted experiments on a saw cut Westerly granite sample under triaxial stress conditions.

Relating Dike Geometry and Injection Rate in Analogue Flux-Driven Experiments

open access: yesFrontiers in Earth Science, 2021
Dikes feed most eruptions, so understanding their mechanism of propagation is fundamental for volcanic hazard assessment. The variation in geometry of a propagating dike as a function of the injection rate remains poorly studied.

Modeling the initiation of others into injection drug use, using data from 2,500 injectors surveyed in Scotland during 2008-2009 [PDF]

open access: yes, 2014
The prevalence of injection drug use has been of especial interest for assessment of the impact of blood-borne viruses. However, the incidence of injection drug use has been underresearched.

A rate-of-injection model for predicting single and double injection with or without fusion

open access: yesInternational Journal of Engine Research, 2023
Models used to predict the instantaneous injected fuel mass are of varied interest in automotive applications, including for providing inputs to CFD calculations or for engine control. While multiple injection strategies are now commonly used in diesel engines, the overall approach may be susceptible to injection fusion, which is defined as two ...
