Solving the oscillating pipe flow problem by the boundary integral equations method
(БНТУ, 2007)In the work, a solution to a problem of oscillatory flow of viscous incompressible liquid in a rectilinear pipe of circular section, completely filled with the liquid was presented. The way of solving flow generated by pressure pulsation and the pipe oscillation to the flow direction was also-discussed. The behaviour of the liquid for the selected spectrum of its frequency and ...2020-06-01 -
