A METHOD OF CALCULATING A RETURN-CIRCUIT RIG WITH CYLINDRICAL BLADING CONFIGURATIONS ACCORDING TO A GIVEN RADIAL PRESSURE GRADIENT,
Abstract
Approximate method is presented for calculating an inverse problem of the axisymmetric flow of a compressible fluid in a blade apparatus with cylindrical boundaries and a constant blockage (the constriction of the interblade passage) along the radius t/b equals const). Since it was not possible to obtain satisfactory results by using successive approximations, the Euler motion equation including derivatives of the radial velocity component was used in this method. It is assumed that the geometrical parameters of the cascade were given and that the working medium flow rate at the mean radius practically equaled the actual flow rate. The total parameters and the distribution of the specific flow rates at the stage inlet and the compression coefficients in the cascade volume were also given. The problem was solved by using a fixed grid and by dividing the cascade meridional projections into n sections along the z-axis and into k segments along the radius. (Author)
