Abstract
In order to calculate energy losses caused by secondary flows in curved channels of any sectional change a mathematical model of a stationary, inviscid (ideal) flow has been applied. The qualitative correspondence between the wall streamlines in a specially curved channel determined numerically (FORTRAN program) and the wall streamlines displayed experimentally in a wind channel has led to the development of a calculation method for three-dimensional boundary layers. Fundamental results of the behaviour of secondary flows due to different effects are given in the present paper.
