Originální abstrakt

A new method of designing of spiral meridional section and spiral spatial shape is introduced in this contribution. The method originates from differential geometry principles and the solution is performed in the curvilinear orthogonal net. The spiral spatial shape is based on the meridional velocity field. The aim of presented solution was achievement of proper hydraulic characteristics. This is ensured due to fluent change of the instantaneous speed of the particle. The fluency is especially endangered in the passage between the spiral and the volute throat. The spiral outlet meridional section shape smoothly changes into circular pipeline section shape in the outlet of volute throat.
