The challenges of wind load to increasingly tall cooling tower become obvious such that researches have been conducted extensively on the effect of wind load on the structure to ensure safety and efficiency of the structures using traditional computational fluid dynamics (CFD) analysis. Other than that, finite element method (FEM) is used to study the structural response to the wind load. However, at present few researches have considered the coupling effect of both fluid effect and structural response of the thin-walled cooling tower. The effect of internal airflow inside the structure is often overlooked as well. In this paper, the method of fluid-structure interaction (FSI) will be employed to study the coupling effects of the fluid and structural response to wind load. By comparing the models with and without internal airflow of the cooling tower, a conclusion of the importance of incorporating internal airflow in the computational model can be made. The computed overall results display the distribution of pressure, fluid velocity, and turbulent eddy through various plots. FSI results will be compared against the CFD analysis of the structure. Obvious deviation can be noticed by the comparison of the results generated by FSI and internal airflow.
