Head Timoshenko V.I., Registration Date 09-03-2003 Organization Institute of Technical Mechanics of the National Academy of Sciences and National Space Agency of Ukraine popup.description2 The object of investigation: thermogasdynamic processes with regard for interphase interacyion in two-phase flows. The purpose of the work: investigation into stability of steady flow regimes for gasdynamic passages depending on ways of action on the flow (mass supply and energy addition, hase transitions). Used methods: information-analytical, theoretical and experimental ones with the use of known and developed at ITM NASU and NSAU methods of mathematical and physical modeling. Results obtained: Mathematical models for calculations of nonsteady two-phase one-dimensional flows are choosen; software is developed and created to study stabilityof steady two-phase one-dimensionalregimes of flows making allowance for phase passages and external heat input; appropriate relationships the program of calculations of non- steady gasdynamic processes in an axisymmetrically mounted reservoir under injection of droplets of fuel components is de- veloped, solid particle-gas interaction in inertial-type devices forphase separation applicable to a laboratory-scale plant is modeled mathematically; more rational applications of cyclones and gills providing minimal energy losses for separation under a maximal effectiveness are determined using emperical relationship for dry inertial dust cleaners; experimental plant for studying phase separation in ineetial type devices is worked out, as a result of tests in dusty and pure air, an optimal arrangement of structural elements and speed regimes praiding a general effectiveness of 92-95% dust collection under dust load ranging from 2 to 8 g/m2 is determined (using a mixture of kvartz sand and chalk with the distribution of dispersivity up to 20% particles less 50 mm); an influence of the dynamics of electrically-controlled fuel valves on ingnition/cut-off of licuid rocket low-thrust engines is studied; a correlation was made between predicted data and results of the bed development.
