摘要

In this study, a two-dimensional, steady, incompressible and laminar flow over the forward and backward facing trapezoidal cylinder is numerically investigated at Reynolds number 20 and 40. Here, by varying the taper angle and axial length of the trapezoidal cylinder, the steady-state wake flow regime, separation bubble length and drag coefficient are characterised. It is noticed that the flow separation point can be at the front or rear edge corners of the trapezoidal cylinder depending upon its taper angle, axial length and flow Reynolds number. It is also observed that when Reynolds number of the flow around the trapezoidal cylinder is increased the separation bubble length increases and drag coefficient decreases in the presence of higher inertia effect.
