Abstract
In this study, the flow past a finite-length tapered cylinder is numerically
investigated via the finite-volume method with Reynolds numbers ranging
from 50-250 and taper ratio l = 1.5. The corresponding lift and drag
coefficients, as well as the Strouhal numbers are presented. The factors
related to the discontinuity, through Reynolds numbers of 100 - 200, in the
lift coefficient, which is related to the wake structure of the tapered
cylinder, are explained. Furthermore, the influence of the wake structure
on the discontinuity in the lift coefficient is discussed. Finally, a
comparison of the Strouhal numbers between the circular cylinder and tapered
cylinder at the same Reynolds number is performed.
