McKinney and published by . This book was released on 1960 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wind-tunnel investigation has been made on modified-square and circular cylinders to determine the effects of fineness ratio and Reynolds numbers on the crosswind drag characteristics. Fineness ratios from 2 to 14 were investigated over a Reynolds number range from approximately 300,000 to 1,650,000 which corresponded to Mach numbers from 0.057 to 0.377.The result of the investigation show that at supercraft Reynolds numbers the drag coefficient of the circular cylinder increases with increasing Reynolds number for all fineness ratios but at low fineness ratios this effect is considerably less than at higher fineness ratios. For circular cylinders in the high fineness-ratio range there is a reduction in drag as the fineness ratio is decreased except for Reynolds numbers of 900,000 and 1,000,000, whereas at low fineness ratios the opposite trend generally occurs. The addition of hemispherical ends to the circular cylinder gave a substantial decrease in drag at a fineness ratio of 3.27 but the effect was negligible at fineness ratios of 5.27 and 10. The finite-length modified-square cylinder gave the reduction in drag over the two-dimensional modified-square cylinder for the complete range of test Reynolds numbers with the lowest fineness ratio giving the lowest drag at Reynolds numbers above 3O0,OOO.

Book Synopsis Aspect Ratio Effects on Circular Cylinder Drag at Low Reynolds Numbers by :

Available in PDF, EPUB and Kindle. Book excerpt: Design of small uninhabited aerial vehicles is hampered by the relatively sparse database available for aerodynamic properties of basic shapes at low Reynolds number (Re). As a step towards remedying this situation, an experimental investigation of the influence of aspect ratio on the drag of circular cylinders at low Re has been conducted. The experiment itself faced the difficulty of measuring the small forces associated with low Re. A novel solution to this problem has been developed and applied in the Patterson Hall low speed wind tunnel at Mississippi State University. Using this method the drag characteristics of cylinders with aspect ratios varying from 16 down to 1 over a Reynolds number range from 10^5 down to 10^4 have been measured. This presentation will discuss the existing database, the present experimental method and the results that have been obtained.

Available in PDF, EPUB and Kindle. Book excerpt: Data are presented which can be used to predict the aerodynamic drag force caused by cylinders having different cross-sectional shapes. Drag characteristics of circular, square, rectangular, triangular, diamond, and elliptical cylinders, as well as a large range of thickness-to-chord ratio symmetrical airfoil shapes, are presented as a function of Reynolds number. In addition, certain Mach number characteristics are discussed.
