Injection rate: A factor in contrast reactions?
Clinical Radiology, 1990A prospective study comparing the frequency of contrast reactions by the rate of contrast injection is presented. One hundred patients undergoing excretion urography with meglumine diatriazoate (18%) and sodium diatriazoate (40%) mixture (Urografin 325) were randomised into slow (mean 0.975 ml/s) and rapid (mean 2.575 ml/s) injection groups.

The Measurement of Injection Rate
Proceedings of the Institution of Mechanical Engineers, Conference Proceedings, 1969In order to obtain the true value of the injection rate of a diesel engine, the following processes are discussed: (1) the Tokyo Institute of Technology's revolving disc method, developed by the authors, which needs no correction, there being few errors; (2) a newly introduced unsteady flow correction method applied to pressure lift method and ...

On the fuel injection rate profile as boundary conditions for diesel spray combustion simulations
, 2020The start of injection (SOI) transition processes present challenges for diesel spray combustion simulations by computational fluid dynamics (CFD). In the previous studies, claims are usually placed on the experimental uncertainties or numerical methods ...

Effect of Variable Injection Rate on Falloff and Injectivity Tests
SPE Western Regional/AAPG Pacific Section Joint Meeting, 2002Abstract Numerous full field water-flooding projects are currently under way throughout the world to improve recovery. In many large oil fields water injection is initiated during the early stages of reservoir development. Exploratory wells are tested for injectivity, and injectors are tested during the field operation.

An on-line measurement method of injection rate of high pressure common rail system
, 2020This paper presents a new on-line measurement method of injection rate based on the injector inlet pressure. The Riemann wave theory is applied to the fuel system, and the mathematical relationship of injection rate (G) and pressure (P) under single ...
