ANALYTICAL AND NUMERICAL ASPECTS OF THE SOLUTION OF THE PROBLEM OF A VISCOUS WEAKLY COMPRESSIBLE LIQUID MIXTURE MOTION THROUGH THE VERTICAL PIPE OF THE CIRCULAR CROSS-SECTION
The paper considers a way of the numerical solution of a system of partial differential equations describing the nonstationary flow of a viscous liquid along a vertical straight pipe of circular cross-section. The result obtained is not final, because the proposed approximation scheme is the simplest and provides only the first order of accuracy. Computer modeling has shown that such an approximation is suitable only for a small time interval.
