Characterization of flow around rectangular bluff bodies at angle of attack

► We describe the flow around rectangular bluff bodies at different angles of attack. ► We identify a region of angles of attack where the lift remains roughly constant. ► The constant-lift region is characterized by three-dimensional (3-D) flow. ► We develop an empirical curve fit to predict the constant-lift region. ► The empirical curve fit is valuable for modeling and simulation purposes.
