REVIEW OF INFLOW TURBULENCE GENERATION METHODS WITH LARGE EDDY SIMULATION FOR ATMOSPHERIC BOUNDARY LAYER

With the rapid development of available computational resources and advanced simulation techniques, large-eddy simulation (LES) has attracted an increasing attention and been widely adopted in solving structural wind engineering problems. For the reliable simulation of wind effects on structures, the generation of inflow turbulence with prescribed statistical characteristics of being consistent with realistic wind flow characteristics in atmospheric boundary layer (ABL) is one of the key issues. And the existing inflow turbulence generation methods for LES can be classified into two main categories:precursor simulation method and synthetic turbulence generation method. This study introduced the rationale of different inflow turbulence generation methods and reviewed their development and applications in structural wind engineering. From the perspective of structural wind engineering, the features and validities of different methods are comparatively analyzed. Finally, several prospects for future research pertinent to inflow turbulence generation methods in structural wind engineering are proposed to solve the existing problems of inflow turbulence generation methods for large eddy simulation in atmospheric boundary layer.
