Flow Interference Between two Circular Cylinders of the Finite Height Vertically Placed in the Turbulent Boundary (Part 1 Pressure Distribution and Interference Force）

摘要

This report presents the interference force arising from various arrangements of two-cylinders of finite height vertically mounted in the turbulent boundary layer. The variations of interference drag and lift force are found to have symmetrical characteristics with respect to the change of the attack angle. Moreover, it is clarified that the drag force has a maximum value at the attack angle ψ＝^^?75°and lift force has two maximum value at ψ＝^^?15°and 165°?170°.
