Atmospheric Boundary Layer for a Full-Size Wind Field Based on Large Eddy Simulation

To study the numerical simulation method for an atmospheric boundary-layer fluctuating wind field, an ideal randomly fluctuating wind was generated by arranging structural measures, such as the roughness element, the spoiler lever, and the grille in a full-size wind field model. Some of the main parameters, such as the height of the roughness element, the spacing of the spoiler lever, and the arrangement of the grille, were analyzed. All of these parameters affected the numerical simulation results, confirmed the effect law, and suggested the possibility of a combined method of the corresponding numerical model by investigating a class C landscape atmospheric boundary-layer wind field. Simulation results satisfied the requirements of the wind structure calculation, achieved a full simulation of the boundary-layer transition, and provided a valuable stream generation method for the subsequent large eddy simulation of the flow around a structure.
