​Hydrodynamics and vibratory–cavitation technology, pumps and sprayers 

 During the period from 2000 to 2011 several vibratory pumps have been developed and patented in the USA (US Patents No.6,315,5333B1; 6,364,622B2; 6,428,289B1; 6,604,920B1; 7,354,255B1; 7,544,048B2; 7,731,105 and etc; US Patent applications: No 10/863,713, US Patent No. 8,353,689 B2) having different productivity and pressure for pumping, transporting and spraying of liquids. They are more economic in production and in operation and are safe to use. Electrical drive of the pumps uses up to 20% less energy compared to existing piston and diaphragm pumps. 
Fig.1.This is a schematic drawing of the elementary design of a vibratory pump. The pump consists of a stand 1, an electromagnet 2, a pipe 3 and a tank with liquid 4. Due to magnetic field fluctuation the pipe 3 vibrates. At a certain frequency liquid from the tank 4 enters one end of the pipe 3, flows within it and then leaves the pipe through the other end. If the exit end of the pipe 3 is connected to a flexible hose it is possible to direct liquid to a technological container. Productivity of the pump depends on a geometrical size of a pipe, frequency of the pipe fluctuation, capacity of an electromagnet and viscosity of a liquid.
This new phenomenon of pumping liquids without a piston was first observed, used and patented by Grigori Lishanski, PhD.

It is necessary to note that the vibratory cavitations idea and technology for the first time were discovered, researched and patented in the USSR more than 30 years ago by Grigori Lishanski, Ph.D in Physics. Therefore the first vibrating devices have received the name of the author: Lishanski's Vibratory Pump and Lishanski's Vibratory Mixer.

Further, being based on results of long-term researches in the USA, the newest designs of vibratory pumps have been created and the technical possibilities of vibratory cavitation technology considerably extended. The specified technology allows pumping and spraying liquids of broad range of kinematic viscosity: water and water solutions, aggressive liquids, oils, liquid soaps and shampoos. 

The phenomenon of vibrocavitation is used as a driving force for liquid substances’ movement, mixing and even mechanical activation of chemical processes upon mixing (so called “mechanochemistry”), with creating new substances.

Mechanochemical technologies as a way to creation of not known before materials and other areas of application 

The most important feature of our vibratory-cavitation technology, or Vibrocavitonic Technology, is the possibility of regulation and managing conditions of the cavitation based on combination and active interaction of processes of vibration, hydraulic impact and vortex streams. The energy of mechanical impact of cavitation on various compounds in liquids (either solutions or suspensions) happens to be enough for breaking chemical bonds in molecules. Even at comparatively soft conditions the induced stresses of the order of (4.8-5.5)*E+42 are significantly higher than strengths of primary chemical bonds in molecules (Average bond energies in covalent compounds are in the range of 200-900 KJ/mol. A conversion factor is I KJ=1.0*E+10 erg). 

Mechanically initiated are many chemical processes: destruction (formation of free radicals), formation of graft copolymers, polycyclic and branched structures, complexes with metallic compounds and combination of various networks. Resulting structures and their properties depend on initial chemical components and their ratios and also on parameters of vibrocavitation and vortex processes. 

Manageable process of cavitations can be realized at certain values of amplitudes and frequency of vibration and geometry of a “reactor” compartment, which may have rectangular or cylindrical shapes. In the case of a rectangular reactor the interaction happens between a liquid and the reactor parts. The cylindrical reactor vibration interacts with vortex streams of a liquid, and the spinning, oscillations, or other interactions of particles with a liquid occur inside the streams. Thus, the vibration and vortex interaction reduces friction of outer layers of vortexes with the reactor walls and reduces liquid’s surface viscosity with an accelerating of the stream flow. 



Materials synthesized with action the vibratory cavitation equipment developed by STG, LLC can be very different and their areas of application correspondingly could be very wide. Our company has focused mostly on energy applications that we consider are technically and economically feasible: 

1. Efficient inexpensive environmentally friendly liquid fuel, heating materials and production of electrical energy without use of oil but based on fossil and non-fossil resources of mostly USA, Canada and other countries outside of Middle East. 

2. Handling of nuclear wastes for vetrification.

3. Development of construction materials having high modulus strength, light weight, high thermo- and oxidative resistance, or being nonflammable or flame retardant. 

The activated mixtures of certain compositions may be used as environmentally friendly, very efficient and inexpensive oil-free fuel. Our work in the area of physicochemical studying of potential fuels is focused on compositions structure, on effect of various physical factors and the optimization of chemical composition, equipment and technological process.
