Second order perturbation method of gas turbine performance calculation
Abstract
The concept of the second-order perturbation method has been introduced and its error analysis is given. The method retains concise physical relationships between variables, and the variable application range is broadened by approximately twice, compared with linear perturbation methods, within same error limit. Some skills to consider the component characteristics and to simplify the performance calculation have been discussed. An operation line has been presented as an example using the second-order perturbation method to prove its engineering availability.
