Use average integral values of parametres at mutual identification of models of gas streams of various dimension

Abstract

Are considered one-dimensional and two-dimensional axisymmetric gas streams, distribution of parametres on which section is received or experimentally, or a settlement way. At the mutual coordination (identification) different levels models GTE or its elements it is offered in section of a flowing part of an air-gas path for non-uniform (one-dimensional) distribution of parameters of two- or three-dimensional model to define average integral parameters and their complexes. Variants of calculation of numerical values of such parameters and complexes and their use for reception integrated (on section) the indicators characterising laws of indestructibility of matter, energy, quantity of movement are analyzed. The variant, suitable for Efficiency calculation in blade machines (the compressor, the turbine), draughts and capacities GTE Is offered.
