Abstract EN
An experimental investigation studies the behavior of heat transferred from a horizontal oscillated cylinder, in case of cross air flow has been carried out.
The investigation studied the effect of dimensionless oscillation frequency (Sc), dimensionless oscillation amplitude (A/D), and Reynolds number on the rate of heat transfer.
The oscillated cylinder has 53 mm O.D, the dimensionless oscillation frequency (Sc) of the cylinder is varied from 0.08 to 0.45, while the dimensionless oscillation amplitude (A/D) ranged between 0.037 and 0.27.
The Reynolds number is ranged between 3×104 and 7.8×104 and the rate of heat flux is varied from 480 to 3000W/m2.
The test rig of the present work has been examined in the case of stationary cylinder and the obtained results are in a good agreement with the available data in the literature of about ±5%, while in the case of oscillating cylinder the rate of heat transfer data indicate a maximum enhancement of about 70% comparing with stationary case at Sc = 0.2 and A/D = 0.27.
The present data have been correlated in a form of Nusselt number as a function of dimensionless frequency (Sc), dimensionless amplitude (A/D) and Reynolds number (Re) with average deviation of about ±4% relative to the experimental results.
