Performance conversion of centrifugal compressors based on predictor corrector method

Predictor-corrector Halley method for nonlinear equations

In this paper, we suggest and analyze a new two-step predictor–corrector type iterative methods for solving nonlinear equations of the type f(x) = 0 by using the technique of updating the solution. This method can be viewed as a predictor– corrector iterative Halley’s method. We also consider the convergence analysis of the proposed method. To illustrate the efficiency of this new method, we gi...

A superlinearly convergent predictor-corrector method

An interior point method for monotone linear complementarity problems acting in a wide neighborhood of the central path is presented. The method has O( √ nL)iteration complexity and is superlinearly convergent even when the problem does not possess a strictly complementary solution.

Predictor Corrector Methods Page 1 Predictor Corrector Methods Predictor Corrector Modes

page 1 Predictor Corrector Methods Predictor Corrector Methods form the basis of the most successful codes (Variable Step Variable Order Methods) for the solution of initial value problems of ordinary differential equations. Briefly, these methods have been successful because they occur in naturally arising families covering a range of orders, they have reasonable stability properties, and they...

A New Optimization Method for Centrifugal Compressors Based on 1D Calculations and Analyses

This paper presents an optimization design method for centrifugal compressors based on one-dimensional calculations and analyses. It consists of two parts: (1) centrifugal compressor geometry optimization based on one-dimensional calculations and (2) matching optimization of the vaned diffuser with an impeller based on the required throat area. A low pressure stage centrifugal compressor in a M...
