AB - 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.
