Dynamics of a laminar flow past a rotating bullet-shaped body*

Numerical simulations are performed for laminar flow past a rotating bullet-shaped body of length-to-diameter ratio $L/D=2$, ranging the non-dimensional angular rotation velocity, $\Omega=\omega R/u_{\infty}$, from $0$ to $0.6$, and covering the Reynolds number range $3200.5$ there are also two transitions, both leading to different swirling flows.
