The study of the effect of the meridional crossover on the stream pattern in a radial-axial turbine

Calculations are carried out for the stream pattern in operating wheels of a radial-axial turbine of the turbo-compressor TKR-14. The meridional profile of the running part of the wheels was made according to A.N.Sherstjuk by using elliptic curve shapes whose center lies at the crossover of the input and output crossections of the wheel. The design of the stream’s structure for an operating wheel of the turbine TKR-14C-26 has been carried out for comparison.
