Aerodynamic forces acting on three circular cylinders having different diameters closely arranged in line
AbstractIn order to predict the aerodynamic forces by a strong wind acting on the H2 Rocket under development in Japan, experimental studies were carried out. A one-hundredth test model of the actual object is composed of a main circular cylinder and two subcylinders closely arranged in line. The pressure distributions around the cylinders and the Strouhal number behind the cylinders were measured for various attack angles α in the range of the subcritical Reynolds numbers. At α=22° and 33°, the drag and lift coefficients of the main cylinder and the individual subcylinders have either a maxima or minima. These phenomena are closely related to the reattachment of the separated shear layer from the upstream cylinder on the downstream cylinder.
