The calculation of flows in the three-dimensional nozzles based on the approximate factorization method // Tomsk State Pedagogical University Bulletin. 2002. Issue 2 (30). P. 20-22

In the given work the method of calculation for equili-brum sub-transsonic flows is offered and the results of its application are given. It is based on the method of approached factorization for the solution of the complete speed potential equation, which has been written down in the conservative form on orthogonal grid, connected with a contour of a nozzle. This method allows calculating flows in nozzles, having the complex form of combustion chamber, particularly the flush-mounted nozzle. The method gives the best correlation with the experiment in comparison with a usual approached factorization method. Such results are explained by using of an orthogonal grid, which improves the approximation of the initial differential equation.

Study of Working Processes in Automatic Emergency Shutdown Valve for a Major Gas Pipelines // Tomsk State Pedagogical University Bulletin. 2004. Issue 6 (43). P. 54-59

Trunk gaslines are key gas movers in Tomsk region. In many cases pipeline loss of integrity, in emergencies, would be associated with explosive processes caused by widening of fatigue fracturing, or entire damage could come from outflow and explosion of flammable transportation fluids escaping from the pipe. Reliable, fast-response stand-alone devices designed to cut-off such emergency sections have become most essential for system-wide operating security. Successfully certified bench and field tests have been performed with an innovative device, AZK-T, offering effective isolation of Tomsktransgaz’s large-diameter pipeline ruptured sections. This device features design simplicity and is easy to operate. Comparisons were made with foreign counterparts to reveal excellent AZK-T performance
