Abstract
Flow patterns around a bluff body are governed by small-scale turbulence and simulation of large-scale turbulence in a wind tunnel is often difficult. A turbulence partial simulation technique that simulates the normalized PSD in a high-frequency sub-inertia range was introduced. In this study, the technique was experimentally investigated using “reduced turbulence intensity”. Base pressure of rectangular cylinders with various slenderness ratios and surface pressures of hexagonal bridge deck models were compared for pairs of turbulences partially simulated. The result showed that the reduced turbulence intensity can be an index of turbulence partial simulation. In addition, the technique can be applied to a hexagonal bridge deck cross section.
