Flow over a body of revolution in a steady turn

GREGORY, PAUL ( 2006)

Experiments investigating the flow over a body in a steady turn require the use of a rotating arm. This apparatus has several limitations, including the restriction of only making one revolution before the body passes through its own wake, which in turn places restrictions on the available time to record measurements. Kinematic transformation using appropriately curved bodies in rectilinear flow overcomes these limitations, but introduces new problems. In this study, Computational Fluid Dynamics (CFD) was used to compare the flow over a body of revolution in a steady turn to the flow generated by the equivalent curved body. To ensure that the angle of attack between the straight body and the curved flow streamlines are preserved for the corresponding curved body placed in straight streamlines, the method of Gurzhienko (1934) was used. This is the first time that modern CFD techniques have been used to analyse the method of curved bodies for three-dimensional applications.
