The phrase "an injection of fluid" is correct and usable in written English.
It can be used in medical or scientific contexts to describe the act of introducing a liquid substance into a body or system.
Example: "The doctor administered an injection of fluid to help rehydrate the patient."
Alternatives: "a fluid infusion" or "a liquid injection".
As for the grainy features of Hugh Grant, he seems to have been weathered for his role by an old-fashioned saddler — a kinder treatment than that meted out to Dennis Quaid, who sports the clenched and stuffed demeanor that usually follows an injection of embalming fluid.
Nevertheless, such an injection of magmatic fluids into an accretionary prism could occur during the subduction of a young plate, which may produce unique geochemical environments along the subduction zone.
A preliminary inversion of the source of the deformation based on a simple elastic model of a buried cavity suggests that a significant injection of fluid occurred at a depth of approximately 450 m below the geothermal plant.
In the last decade, a handful of energy companies have begun extracting natural gas from the Marcellus and Utica Shales underneath Pennsylvania via hydraulic fracturing, or fracking, a much-reviled practice that involves the release of gas or petroleum via a high-pressure injection of fluid through a narrow shaft bored into the ground.
The day I woke up at about six months pregnant, so dizzy that I fell with my child in my arms, was the first and thankfully only time I had to go to the hospital for an intravenous injection of fluids.
While it is possible children are more vulnerable in Africa because of malnutrition and the severity of diseases such as malaria, doctors say there is no clear reason why an injection of a large amount of fluid through a 15-minute drip – known as a bolus – would be more dangerous in Africa than in Europe.
The reverse pressure pulses that manifested in the loop as a result of fast injection of fluid has been mathematically characterized by solving basic fluid balance equations.
This model addresses the effects of the diffuse fluid pressure increase, and is useful for engineered applications such as the injection of fluid into a reservoir that may cause an increase of fluid pressure beneath a caprock, and for sedimentary sequences during normal digenetic processes of burial and fault activation.
Injection of fluid through a porous bounding heated or cooled wall is of general interest in practical problems involving film cooling, control of boundary layer, etc.
