title = "ANALYSIS OF CORNER RADIUS ON THE FREE OSCILLATING CYLINDER WITH HEAT TRANSFER AND FLOW PATTERN AT LOW REYNOLDS NUMBER",
abstract = "Flow-induced vibration (FIV) of the modified single-cylinder with a change in corner radius has been investigated in a laminar flow regime with Re=100 and Pr=0.7. The corner radius (r: corner radius,:R cylinder characteristic length) is changed from 1 to 0 and two angles α ; 0° and 45º are used. The Cylinder is elastically supported with heating at a constant temperature at the boundaries. Vibrations are restricted to the transverse direction. Computation is carried out with a fixed mass ratio ∗ 10 m = and varying reduced velocity Ur = 2 ~8 . The two-dimensional incompressible Navier-Stokes equations and energy equations are coupled together. Navier stokes equation used with FIV equation of elastically supported cylinder to have flow solutions. Lock-in synchronization can be observed at 5 Ur = and Re=100 at ∗ 1 r = which leads to severe vibration and maximum vibrational amplitude A D while amplitude modulation has been observed at 5 Ur = for the square cylinder. Based on the mode of vibration whole study has been divided into 4 ranges of vibration. Mode-I, where the amplitude is very low; Mode-II, fluctuating amplitude known as hysteresis (Beating); Mode-III; amplitude is at the maximum because of lock-in synchronization; Mode-IV, normal vibrational amplitude. Different modes are compared with the change in Ur , ∗ r and α. The effect of Ur is visible on the Nusselt number as more vibration leads to a high value of averaged Nusselt number Avg Nu . Vortex shedding is changed from C(2S) to 2S as the corner radius is modified. Results give a deep insight into heat transfer getting changed by changing three different parameters and will make a base for future study of tube bundles in heat exchangers with FIV.",
