%X 光热发电吸热塔在运行条件下对周围空气形成加热&#65292;易导致吸热塔周围出现热对流现象。热对流对临近区域飞行运行安全可能造成一定影响。本文基于计算流体方法建立了光热发电吸热塔三维计算模型&#65292;分析了吸热塔顶部不同高度的温度场、湍流强度以及涡流耗散率的大小&#65292;并基于涡流耗散率的大小评估了吸热塔对飞机颠簸的影响。结果显示&#65292;在当前条件下吸热塔所形成的局部热湍流影响的范围较小&#65292;飞机在距离吸热塔高50 m以上及吸热塔后方600 m范围以外运行基本没有影响。<br>In solar thermal power generation systems, the heat absorption tower heats the surrounding air during operation, which can induce thermal convection in its vicinity. This thermal convection may pose potential risks to the flight safety of aircraft operating in adjacent airspace. To investigate this phenomenon, a three-dimensional computational model of the heat absorption tower was developed using computational fluid dynamics (CFD). The model was employed to analyze the temperature field, turbulence intensity, and eddy dissipation rate at various heights near the top of the tower. Based on the eddy dissipation rate, the impact of the heat absorption tower on aircraft turbulence was evaluated. The results indicate that, under the given conditions, the spatial extent of local thermal turbulence generated by the heat absorption tower is limited. Specifically, the influence on aircraft operations becomes negligible at altitudes exceeding 50 meters above the tower and at distances greater than 600 meters downstream of the tower.
