Opis:: The paper deals with the analysis of power factors acting within the boundary layer for different types of flow: convergent, gradientless and diffuser. Based on the considered formation mechanism of boundary layer separation, a hypothesis about the possible influence on structure and character of a separated flow by changing the gradient of the tangential stresses in the boundary layer was proposed. This impact is proposed to realize by means of the longitudinal finning of diffuser. Verification of the concept is performed on the basis of numerical flow investigation and available experimental data.

Tytuł:: Two-tier low pressure cylinders for condensing steam turbines

Opis:: The paper deals with new construction of low pressure cylinder (LPC) for condensing steam turbines. The flow path of these cylinders is formed on the base of new two-tier stages. As opposed to well known Baumann’s stages newer two-tier stages is a combination of two independent stages with own blades set. Such construction allows to decrease the number of LPC in the existing turbines or to ensure their operation with very high vacuum in the condenser or increases in 1.5 times power capacity of new turbines without increasing of the last stage blade length and LPC number.
