The volume provides an exhaustive catalog of common standard day corrections for gas turbine gas path parameters, explores their history, and, most importantly, provides a mathematical framework for the derivation of these important normalization factors. Although use of these corrections is common practice within industry, government, and academia, their genesis, and, in particular, how they can be derived from simple principles, is not general knowledge among many of those who use them on a regular basis. This book elucidates calculation of these important coefficients. Standing as a one-stop source on derivations and a methodology for additional parameter correction refinements, Gas Turbine Parameter Corrections, is ideal as a desk reference for practitioners and researchers, as well as supplemental instruction for university courses on gas turbine performance, control, and DPHM (diagnostics, prognostics and health management).
