Flow Numbers and Their Summation: Development of the Concept of a Component Flow Number Applicable to Gas Turbine Fuel Systems Available to Purchase

In this article the concept of a component flow number is developed and for a particular example good agreement is shown with an empirical expression. An expression is derived for the flow number of two components in series—this is confirmed by experimental evidence. A rapid computational method for a combined flow number is given and also a single change in a flow path and parallel flow paths are discussed. Conclusions are drawn concerning the dependence of flow number on the physical variables for single and multi‐component flow systems.
