SIMULTANEOUS-MEASURING DISPLACEMENT, PRESSURE, AND AERODYNAMIC FORCE OF OSCILLATING SQUARE CYLINDER : Aerodynamic characteristics of 2D cylinder in uniform flow using hybrid technique Part 1

Abstract

In our former paper, the concept and accuracy verifications of the experimental system using the hybrid technique are presented to verify the interactions between the bluff body and the surrounding flow (New Hybrid Aerodynamic vibration Technique ; NHAT). In this paper, first of all, the pressure-estimation performances of NHAT are examined as the final step of accuracy verifications. In the next place, simultaneous-measuring results among displacement, pressure, and aerodynamic force of square cylinder in uniform flow are shown in case of one parameter when the vortex-induced oscillations occur dominantly. The results of parametric studies concerning with the aerodynamic characteristics will report in the next paper.
