NUMERICALLY STUDY EFFECTIVENESS OF CONTROL SURFACE ON AERODYNAMIC OF BRIDGE DECK BY USING IMMERSED BOUNDARY METHOD

The study of the aerodynamic stability of long-span suspension bridge is very important in design state. One of control methods is to change the flow over the bridge deck, so that the aerodynamic forces will be changed. This study investigates the effectiveness of control surface attached to bridge deck by using the immersed boundary method. The results show that the values of the aerodynamic forces are reduced after controlling the control surfaces...
