Wind-Induced Response of the Solar Chimney

Abstract:

Article Preview

Wind-induced response was investigated on the chimney of a 100MW solar thermal power station. Firstly, dynamic characteristic of the chimney was analyzed and the first eight vibration mode shapes and frequencies were obtained. Wind velocity time-history simulation was then conducted utilizing harmonic superposition method with Fast Fourier Transformation. Followed that, transient dynamic analysis was carried out to obtain the wind-induced response and the wind vibration displacement coefficient calculated. Numerical results indicate that the maximal displacement and acceleration of the chimney appear on the top with a value of 0.5593m and 0.1933m/s2 respectively. Wind vibration displacement coefficient on the chimney increases with height with an average value of 2.303.
