ABSTRACT = {This paper presents a two-dimensional fluid-structure interaction numerical simulation of fluid flow over two horizontal heat exchange cylinders 
affected by a flapping reed in a domain. The reed is a thin flexible sheet made of elastic material with one end fixed on the trailing edge of the 
upstream cylinder. The effects of the reed length and the cylinder spacing on the periodic oscillations of the reed, the flow field and the heat transfer 
of the downstream cylinder. The results show that the oscillation of the reed in this paper is a single-period oscillate model. Compared to the case of 
cylinder without any measurement of heat transfer enhancement (clean cylinder), the heat transfer performance of the cylinder with the reed could be 
enhanced under certain conditions. For the case of the cylinder spacing S*= 1.5, as the length of the reed increases, the heat transfer of the 
downstream cylinder increases by up to 14% compared to the clean cylinder, while the domain resistance coefficient is almost unchanged. For the 
cases of cylinder spacing S*= 2.0, as the length of the reed increases, the heat transfer of the downstream cylinder gradually decreases, but the 
domain resistance coefficient gradually increases to 12%.},
