Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The direct problem of thermal non-destructive testing disperse suspension phases at its gravitational discharge from the reservoir through flat nozzles A.V. RYAZHSKIKH, A.A. KHVOSTOV, Yu.Yu. GROMOV, I.N. KACHKIN, O.A. SEMENIHIN Based on the classical equations of the interpenetrating continuum for two-phase media, under the assumption of unidirectional flow in the regime of ideal displacement under the action of gravity, the absence of a restructuring of the dispersed phase topology and the dissipation of mechanical energy into thermal, and phase transitions and the constancy of thermophysical characteristics, a mathematical model for the identification of the temperature contrast of the dispersion phase in a flat vertical nozzle in the form of a boundary-value problem for a system parabolic equations for the local temperatures phases with boundary conditions of the second kind in 2-D format. After the geometric averaging of the obtained system, an exact analytical solution was found, with the help of which the dependence of the temperature contrast on the relative volume content of the solid phase on the example of a water-coal fuel was analyzed, which showed a satisfactory sensitivity of the application of thermal control. Keywords: suspension, flow, heating, temperature contrast, solid phase. DOI: 10.25791/pribor.10.2018.236 Contacts: E-mail: gromovtambov@yandex.ru Pp. 49-54.
