Local heat transfer at the end faces channel profiles turbine nozzles for intense secondary flows

А.А. Kaschenko
Annotations languages:

An experimental study of local heat transfer at the end surfaces of the channel profiles turbine nozzles in secondary currents, the intensity of which varied by reducing the height profiles (h) and increasing the thickness of the boundary layer (вх) accumulated at the entrance to the object of study. The data characterizing the distribution local heat transfer coefficients on the end surface in a wide range of characteristic parameters.
Keywords: local heat transfer coefficients, the end surface of the channel profiles turbine nozzles, secondary flow
