Tip vortex cavitation suppression and parametric study of an elliptical hydrofoil by water injection
The Physics of Fluids, 2023Tip vortex cavitation (TVC) affects hydrodynamic performance and can cause drastic vibration and noise; therefore, it is crucial to predict the evolution of TVC, understand its generation mechanism, and determine methods to control it.

In-cylinder water injection is a promising approach for reducing NOx and soot emissions from internal combustion engines. It allows one to use a higher compression ratio by reducing engine knock; hence, higher fuel economy and power output can be ...

Journal of the American Medical Association, 1945
To the Editor:— I should like to comment on your answer to an inquiry regarding the usefulness of injections of distilled water (The Journal, Oct. 20, 1945, p. 584). You state that "there appears to be no basis for preference for water over isotonic solution of sodium chloride." I can think of at least three conditions in which this statement would ...

"The objective of any water-injection operation is to inject water into the reservoir rock without plugging or permeability reduction from particulates, dispersed oil, scale formation, bacterial growth, or clay swelling." Introduction Ideally, injection water should enter the reservoir free of ...

Proceedings of International Petroleum Exhibition and Technical Symposium, 1982
Abstract It is generally acknowledged that the first waterflood occurred as a result of accidental water injection in the Pithole City area of Pennsylvania in 1865 (1). As long ago as 1880 it was concluded that water, finding its way into a wellbore from shallow sands, would move through oil sands and be beneficial in increasing oil ...
