Comments on 'Effects of viscous dissipation on the heat transfer in forced pipe flow. Part 1: Both hydrodynamically and thermally fully developed flow [Energy Conv. Manage. 2005; 46: 757-769] and Part 2: Thermally developing flow [Energy Conv. Manage

摘要

We comment on the papers by Aydin. These papers treat the same problems as those studied by Ou and Cheng, namely the effects of viscous dissipation on forced convection in a pipe of circular cross section. In [1], paper [3] is cited, but [4] is not mentioned. Paper treats the case of boundaries with constant heat flux (CHF), called the H boundary condition by Shah and London, while paper treats boundaries with constant wall temperature (CWT), the T boundary condition. Both the CHF and CWT cases are considered in [1,2]. Since cover the same ground as [3] and [4], one can question the need for them.
