The Frictional Interaction In Electrical And Thermal Fields Of Metal Friction Pairs
A.Kh. Janahmadov, A.I. Volchenko, E.S. Pirverdiev, D.A. Volchenko, N.A. Volchenko, D.Y. Zhuravlev
The article examines the origins and development of the electrical and thermal explosions in the polymer lining subsurface layers, as well as the discharge penetrating through the layers of micro-protrusions.
The Development Of Mathematical Models With “Skin-Factor” For The Petroleum Reservoir Filtration
Ab.G. Rzaev, S.R. Rasulov, I.A. Abbasova, S.N. Rahimova
The paper proposes a modified Dupuis formula, which describes the filtration process based on “skin-factor” of the polluted near oil-well area. The viability of proposed model is provided. The regularities of the reaction-regeneration cycles are established.
The Safety Management Based On The Probabilistic Risk Assessment
The probability estimation of potentially dangerous (basis) events is conducted on the basis of the current values of the risk factor given the risk significance of the individual components responsible for the flight safety. The flight is viewed as a random process described by a stochastic differential equation. The author raises the issue of absolute and guaranteed safety.
The Mass-Transfer At The Wastewater Countercurrent Extraction Processes Inside Of The Spray Tower And Its Modeling
The wastewater treatment technology is developed on the basis of the solvent extraction using a spray extractor. In the paper the optimal process parameters are proposed and the consumption rates for continuous and dispersed phases are justified. The research results of the wastewater treatment produced by the paint and varnish manufacturers from butylglycol, phenilizopropanol, acetic acid and acetylacetone are included in the paper. The mathematical model of process is proposed; the specific area of the contact surface, the distance between the extractor cells, the coefficients of mass-impact and mass-transfer of the phase components are defined; the component concentrations in opposite phases and the aggregate height are calculated.
The Deformation And Break Up Of Drops And Bubbles In The Isotropic Turbulent Flows
G.I. Kelbaliyev, L.V. Guseynova, S.R. Rasulov, G.Z. Suleymanov
The research paper is dedicated to the phenomena of deformation and break up of drops in the isotropic turbulent flow. The phenomena has been analyzed, modeled and compared with the experimental data. As a result of that research, the analytical solution is provided for the given problem, the expressions for estimation of the deformation level and the break up frequency depending on Red and Mo numbers have been obtained.
