Experimental study of dynamic coefficients of hydro-monitor jets

Article preview

The beginning, laid in the USSR in 1953, of hydraulic stripping of coals and strong rocks in the mining industry, led to a number of domestic and foreign experimental studies of nozzles in order to determine those of their profiles, which provide maximum forces on the bottom hole - preventing the flow.

Resistance of a layer of deposits on a wall at destruction by a water jet

Variational method of solution of dynamic problem for elastic half-space

Article preview

Impulsive loading of the surface of an elastic half-space and "dome-shaped" distributed pressure encountered in the determination of contact problem stresses in hydraulic fracturing of massifs was considered in the works on the basis of solving equations by the method of separation of variables.

About formation of the Reynold's criterion function

Article preview

The question of sufficient conditions supplementing the necessary general criterion conditions of similarity in hydrodynamic problems is equivalent to the question of the uniqueness of the solution of the system of basic equations.

Mathematical description of the drive of the rotary-feeding mechanism of a drilling machine

Article preview

Mathematical models of the drive of rotary feed mechanisms (RPM) of roller cone drilling machines, necessary for the selection of operational modes of control of drilling processes and design of systems of automatic regulation of its parameters, are poorly studied.

Экспериментальные данные в схемах расчета гидромониторной струи

Article preview

Как известно, сложный механизм незатопленных струй недостаточно изучен и результаты соответствующих экспериментальных исследований пока слабо поддаются гидромеханической интерпретации. В этих усло­виях потребность в практических расчетах привела к необходимости исследований, предназначенных для выработки эмпирических формул узко ограниченной, частной, областью приложения. Такой подход к изучению струй, когда используются заранее без достаточно строгого гидромеханического обоснования полученные из опытов закономер­ности, только условно можно считать правильным ...

Investigation of kinematics of a free unsubmerged jet

Article preview

In the development of scientific bases of hydromechanization of mining works the theory of motion of a free unsubmerged jet plays a great role. There is quite an extensive literature on the structure of the jet leaving the nozzle, instability developing in it, jet decay, influence of conditions preceding its exit, resistance of the surrounding (much less dense) medium and dynamic properties of the jet. Nevertheless, even in the experimental field, the existing data cannot be recognized as exhaustive for the creation of a hydraulic theory of the jet.
