Laminar flow past a spinning bullet-shaped body at moderate angular velocities

We present a numerical study of the flow past a spinning bullet-shaped body of length-to-diameter ratio L/D=2, focusing on the evolution of the forces and flow regimes that appear depending on the values of the two governing parameters, namely the Reynolds number, Re=ρw∞D/μ, and the dimensionless an...

Description
Summary:We present a numerical study of the flow past a spinning bullet-shaped body of length-to-diameter ratio L/D=2, focusing on the evolution of the forces and flow regimes that appear depending on the values of the two governing parameters, namely the Reynolds number, Re=ρw∞D/μ, and the dimensionless angular velocity, Ω=ωD/(2w∞), where ρ, μ and w∞ are the free-stream density, viscosity and velocity, respectively, and ω is the angular velocity of the body. The parametric study covers the range 0≤Ω≤0.4 for Re
