Abstract

The article presents the results of computer modeling and preliminary hydraulic studies of the injection pipe rotary
section of a suction dredger with different cross-sectional shapes and the optimal, oval cross-sectional shape of the
injection pipe rotary section is selected. Computer simulation has been carried out in the Solid Works application software
package, and the flow simulation of an incompressible viscous fluid in the rotary sections of the injection pipe has been
carried out on the basis of the Cosmos Fleo Works mathematical package. Laboratory studies on models made of Plexiglas
of various cross-sectional shapes (round, rectangular, oval) have been carried out. After conducting the research, it has
been found that using the optimal, oval cross-sectional shape on the turning sections of the dredger suction pipe, it is
possible to reduce hydraulic resistance by 15…20 % and increase the productivity of the dredger as a whole by 10…15 %.
