Low Reynolds

A discussion is given of the current state of knowledge of vortex streets behind circular cylinders in the Reynolds number range 50 to 160. This was prompted by Gaster's (1969) report that he could not find the transition at a Reynolds number of about 90 observed by Tritton (1959) and Berger (1964a). A further brief experiment confirming the existence of the transition is described Reasons for rejecting Gaster's interpretation are advanced. Possible (mutually alternative) explanations of the discrepant observations are suggested.

Mesh Technique

The vortex-induced vibration and heat transfer of circular cylinders at low Reynolds number (Re=50~180) was numerical analyzed. The cylinder motion was modeled by a mass-spring-damper system, and the motion equation of the cylinder was solved by Newmark-β method, and then the cylinder velocity was written into the UDF of Fluent, finally, the dynamic mesh technique was used to solve the coupling between the cylinder and flow. The results including “Lock-on” and “Beat” phenomena were obtained, and the effect of mass ration on "Lock-on" was analyzed, furthermore, the influence of vortex-induced vibration on convective heat transfer was also discussed.
