The results show that the most effective flow control at high angles of attack is achieved with the O-give nose forebody geometry.</p><p>For the O-give nose geometry, impacts of various body components including fairings, forebody wings and aftbody fins on the overall control performance were investigated. Effects of strake height, length, axial and azimuthal locations were studied, and an optimal rectangular strake planform was determined. Off-surface flow visualizations were conducted to study the flow fields associated with O-give, hemisphere and elliptical forebody geometries, and the optimal strake in combination with O-give forebody. Numerical simulations using FLUENT were conducted at low angles of attack for the baseline model with O-give and hemispheric forebodies. Simulations were performed at different Mach numbers for the O-give nose. The results obtained from the simulations were compared to that of the experiments.</p> 2010-06-14 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1271365316 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1271365316 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
