Impact of Water Injection on Emissions of Nitrogen Oxides from Aircraft Engines
… NOₓ reduction technique has been proposed where water is injected in different regions of a gas turbine engine to cool down the peak flame temperature and decrease NOₓ production. In previous studies, water injection has been simulated on existing engine models instead of co-optimizing the engine …

A tissue tensioner to limit water injection during high pressure water jet debridement
… technology that uses two high-speed impinging water jets to excise necrotic tissue. However, this device potentially causes accidental injection of water into healthy tissue beneath the wound bed, which can cause injury and necrosis in the healthy tissue. The purpose of this thesis is to …

An investigation of the Briggs' Vapor Injection Apparatus
… that there could be designed and built a water injection device that would operate under the conditions which were imposed on the Briggs' Vapor Jet for the purpose of this investigation. If, however, such a device be built, it is felt that it must be subject to controls of many kinds based …

Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
… the optimal combination of two solvent slugs and injection/production strategy to optimize the injection process for improving the CSP in thin heavy-oil reservoirs. It is also shown that other ways of improving CSP is either to repressurize the system using water injection, i.e., conducting cyclic …
