efficient water jet for injection
Water injection (engine) – Wikipedia
Certain other engines can benefit far more from the use of water injection. Typical pulse jet engines have extremely poor fuel efficiency, specific fuel consumption, and thrust. Water injection has been proven to use the waste heat that causes a pulse jet to glow red hot and convert it into thrust.
Injector – Wikipedia
Jet pumps are commonly used to extract water from water wells.The main pump, often a centrifugal pump, is powered and installed at ground level.Its discharge is split, with the greater part of the flow leaving the system, while a portion of the flow is returned to the jet …
Characterization of jet injection efficiency with mouse
The cartridges can hold a total volume of 110 μl, and the expelled volume can be set to either 50 or 100 μl (0.05 or 0.1 ml). The upper cartridge inner diameter where the plunger travels is D p = 4.57 mm, whilst the orifice from where the jet exits is circular with a diameter of D j = 157 μm, which was previously reported to provide maximum injection efficiency [].Author: Jeremy O. Marston, Carla M.R. Lacerda
Power-efficient controlled jet injection using a compound
Oct 12, 2007· I have read a lot of threads and articles on jet drives, and their efficiency related to boats driven by propellers. I keep seeing claims that jet drive efficiency can be nearly as high or higher than that of propeller drives. The claim seems to be that the jets are more efficient at higher speeds, say 25 to 60 knots than propeller driven craft.

Prediction of Turbulent Jet Mixing Noise Reduction by Water Injection Max Kandula’ ASRC Aerospace, NASA Kennedy Space Center, Florida 32899, USA A one-dimensional control volume formulation is developed for the determination of jet mixing noise reduction due to water injection. The analysis starts from the conservation of

Ltd.) was performed into each sample. …Cited by: 1
The Efficiency Rate of a Steam-Water Injector
to jet mass flow rate ratio, axial injection location, water injection angle, number of injectors, method of injection (jet type or spray type), droplet size, water pressure, and water temperature. Optimal injection parameters need to be determined for the design of efficient water deluge system. Data of Zoppellari & Juve5 and of Norum7 suggest …

The operating costs of Mazzei injectors are lower than less efficient systems, and Mazzei injectors are trouble-free because they have no moving parts. How a Mazzei Venturi Injector Works. When pressurized water enters the injector inlet, it is constricted toward the injection chamber and changes into a high-velocity jet stream.

The efficiency rate of the steam-water injector inj is presented with: inj L cwnozz mc d (1) where L+cw nozz – is the efficiency rate of the Laval nozzle and the cold water nozzle mc – is the efficiency rate of the mixing chamber d – is the efficiency rate of the outlet diffuser.
Is water ever injected into a aircraft jet or piston engine?
Water jetting equipment using high pressure water pumps is used to direct high pressure water streams against material to clean or cut it. The streams of water released by water jetting and water blasting equipment is normally 5,000 PSI to 40,000 PSI. In an efficient water jetting system, pressure is …

The "water injection era" I sometimes think water injection was merely an engineering "hack" to help bridge the technology gap between the large, modern airframes of that era, and the puny engines used to fly them. Granted, metal airframe construction dates to the late 1920’s, and jet engines didn’t appear until around 15 years later.
Steam Jet Heaters Steam Jet Heaters Overview. Steam Jet Heaters utilize the principal of direct injection to mix steam with a cold liquid uniformly. Operation is efficient because the heat in the steam is absorbed by the liquid being heated to approximately 10% of liquid saturation temperature.
Direct Steam Injection Heaters A direct steam injection heater provides a cost-effective method to heat water and other fluids by injecting steam directly into the fluid. The direct injection heater is designed to handle a wide range of flow rates and deliver hot fluids at precise temperatures.
Oct 07, 2006· Water was used to increase thrust of the engines during take-off, and is the prime reason for the huge streams of black smoke coming from the engines during take-off. The latest versions of the B-52 have been fitted with more modern jet engines which are much more efficient, and don’t require water injection.Status: Open
