The present paper analyses the capability of a modified indicial approach in determining the aerodynamic admittance functions of bluff bodies by means of Computational Wind Engineering simulations. The method is applied to a bridge deck section in order to pursue two main objectives. Firstly, the extension to bluff bodies of the aerodynamic admittance concept is discussed. Secondly, the sensitivity of the flow field around the section and of the aerodynamic admittance function to the incoming flow characteristics is analyzed. Computational results are compared with the experimental ones if the latter are available.

Abstract

The present paper analyses the capability of a modified indicial approach in determining the aerodynamic admittance functions of bluff bodies by means of Computational Wind Engineering simulations. The method is applied to a bridge deck section in order to pursue two main objectives. Firstly, the extension to bluff bodies of the aerodynamic admittance concept is discussed. Secondly, the sensitivity of the flow field around the section and of the aerodynamic admittance function to the incoming flow characteristics is analyzed. Computational results are compared with the experimental ones if the latter are available.
