Abstract

The gas-dynamic  calculation of three-dimensional current in view of the heating caused by friction of gas about finishing disk, in turbo-expander step of expander-compressor  unit with use of program complex ANSYS CFX it is carried out. The comparison of  settlement data with results of industrial tests is executed. The proved actions on improvement of cha-racteristics of turbo-expander are offered.
