Abstract

Baranyi et al. [1] presented an experimental and numerical study, focusing on fluid dynamics and heat transfer of a heated circular cylinder in air cross flow. Although their paper interprets the results in a quite different manner to previous literature, their experimental results were quite consistent in some aspects with previous data in the literature. The purpose of this commentary is to eliminate any misunderstandings for readers of Ref. [1] and to point out that their data do reasonably confirm the effective temperature concept proposed in the literature.
