FIELD SYNERGY NUMBER VERSUS STANTON NUMBER

Abstract

In this study, a look on field synergy number (Fc) is presented. The field synergy number (Fc) was introduced in literature in 21st century by Professor Zeng-Yuan Guo and co-workers. It is defined as the ratio of the Nusselt number (Nu) to product of Reynolds and Prandtl (Re and Pr) numbers. As a result, Fc is defined in the same way like the Stanton number (St) although the Stanton number (St) was named after Thomas Edward Stanton (1865-1931). Based on this study, it is clear that existing dimensionless number in literature i.e. Stanton number (St) can be used instead of the field synergy number (Fc) because there is no need to change the name of the Stanton number (St) to the field synergy number (Fc) as well as the Stanton number (St) can be used in mass transfer applications.
