Abstract

In this paper, inline and transverse forces on elliptical cylinder immersed in the wake of circular cylinder are carefully evaluated. The effects of variations on characteristic dimension, inline and transverse position of the elliptical cylinder are determined through numerical simulations at Re =1300 based on the diameter of circular cylinder. The results indicate minute effects due to variation on inline positioning. However, variations on transverse positioning and characteristic dimension have profound effects on the amplitude of lift coefficient as well as frequency peaks in Power Spectral Density (PSD). 1:1 frequency lock-in is observed for all simulation cases.
