... aspect ratios of 2–15. Test were conducted in the subcritical regime with Reynolds numbers ranging 9300–105,000. Tip vortex effects, which vary with aspect ratio, are shown to impact the cylinder surface pressure, drag coefficient and wake Strouhal numbers though Reynolds number effects are minor...

... 30 07 2010 Study of parachutes is very important in aerospace industry. In this research, the effect of various Reynolds numbers on a parachute with a vent and without a vent at the top on drag coefficient in a steady and turbulent condition is studied. After a complete research...

... of the triangle with the vertex at the downstream side stabilized the flow and delayed the onset of vortex shedding. Significant differences of drag coefficient, wake length, and velocity distributions were found between the two orientations of the equilateral triangle. Equilateral triangular cylinder...

... 03 03 2009 Exact solutions of the equations of momentum and energy of a circular disk in a uniform incompressible flow directed along its axis of symmetry are obtained. Laminar, irrotational and inviscid flows were assumed. The solutions for the pressure distribution, drag coefficient...

... 14 10 2008 The inter-relationship of drag coefficient C d and Strouhal number St in a turbulent wake was experimentally investigated for ten cylinders of the same characteristic height d but of different cross-sections at Re = 2600 and 6000, based on the freestream velocity...

..., and the gap between the tandem trailers on the aerodynamic drag were determined. The effects of vehicle geometry, vehicle speed, and the gap size were investigated and the drag coefficients were computed. CFD software STAR-CD with an expert tool, es-aero, was used for all the analyses reported in this paper...
