Abstract

A study investigates the aerodynamic characteristics of the circular cylinder without support interference by using an magnetic suspension and balance system (MSBS), along with the investigation of a finer fineness ratio region is required for construction of a complete database. To elucidate the relationship between the aerodynamic force acting on a freestream-aligned circular cylinder with a low fineness ratio and the resulting wake structure, it is necessary to measure the aerodynamic force and the base pressure, as well as consider the flowfield, when the fineness ratio is systematically varied below a value of 0.75, whereas the existing data of drag coefficients in this region were scattered. The objectives of this study are to determine whether there exists a fineness ratio between 0.50 and 0.75 that maximizes the drag coefficient and to show the characteristics of aerodynamic forces without support interference.
