General formulation of practically applicable fundamental approach for development of engineering applications in systems with dynamically appearing and disappearing fractal structures is proposed. The approach is illustrated on the low-temperature pyrolysis of butane/propane mixture being pumped via the liquid tin and bismuth alloy preserved at the temperature 200 ± 20°C in the U-shaped test glass. Other prospective engineering applications of the approach are proposed on the base of analysis of selected experiments described in literature.
The focus of the study is experimental setups and conditions leading to pyrolysis (cracking) of such gaseous hydrocarbons as methane, mixed propane and butane, at the temperatures of the heater below 200˚C. The process was mechanically assisted by putting the substances being decomposed into a dynamic interaction with the fractal interfaces of cracks in titanium dioxide films, as well as in tin and bismuth alloy. During a trial, the alloy was periodically heated and cooled so that it changed its phase state, and fractal interfaces were created between its surface and the gases. The interaction of the gases with fractal surfaces of the alloy being produced by mechanical fracturing made it possible to obtain gas cracking even at the lower temperatures of the heater (150˚C). It should be noted that at this temperature, the heater couldn't melt the alloy in the heated volume with the gas.
In this paper one presents an analytical model of accretion disk magnetosphere dynamics around supermassive nonrotating black holes in the centers of active galactic nuclei. Based on general relativistic equations of magneto hydrodynamics, the nonstationary solutions for time-dependent dynamo action in the accretion disks, spatial and temporal distribution of magnetic field are found. It is shown that there are two distinct stages of dynamo process: the transient and the steady-state regimes, the induction of magnetic field at t > 6:6665 x 1011GM/c3 s becomes stationary, magnetic field is located near the innermost stable circular orbit, and its value rises up to ~ 105 G. Applications of such systems with nonrotating black holes in real active galactic nuclei are discussed.
The report continues reporting of results of an ongoing research verifying a hypothetic energy generation mechanism for reengineering of Gritskevich’s Hydro Magnetic Dynamo (HMD). The HMD technology is a patented technology for electric power generation. It was invented in Russia and deployed in a semi-industrial scale (1.5 MW power unit) in Armenia in 1992. After its successful exploitation during 5 years no more units were assembled. Nowadays the technology needs verification of its physical mechanisms for its successful reengineering. The aim of the report is to present current results of an ongoing theoretical and experimental research of hypothetic physical mechanisms providing energy generation in the unit. It is written without disclosure of its construction and technical details. Thus the theory of hypothetic energy generation mechanisms is described in a general way. The reported experimental results provide only partial support for the theory. They should be independently reproduced and verified.
