摘要

The ratio of inertia to friction forces, characterized by the Reynolds number, influence gas turbine performance very significantly. We describe how the use of the Reynolds Number Index can simplify performance calculations. The correlation of Reynolds number corrections with real data is illustrated through use of a pipe flow analogy and Moody charts.
