| 目的 探究自旋转效应对全局和局部加热条件下热加载装置内部流动与传热特性的影响，以指导环境试验用热加载装置的工程设计。方法 通过数值模拟研究全局和局部实际加热情况下自旋转热加载装置内速度场与温度场分布特征，以及加热壁面平均传热性能，获取旋转作用对温升速率、目标平衡温度、温度不均匀度等热加载装置关键技术指标的影响。结果 装置内流动速度随旋转作用的增强先减小、后增大，当装置以1 000 r/min旋转时，内部空气流动受到了旋转作用的抑制；当旋转速度高于1 000 r/min时，旋转作用又促进内部空气流动。全局加热情况时，热加载装置在0~10 000 r/min的温升速率为20.92~34.43 K/s，装置内部平衡温度随旋转速度增大先增加、后略有减小；局部加热情况时，温升速率则为3.47~4.49 K/s，装置内部平衡温度在1 000 r/min最高，且装置内温度不均匀性因受到侧壁受热不均匀的影响而更加复杂。结论 热加载装置的设计需充分考虑旋转速度对装置温升速率和平衡温度的影响，加热面积越大，装置内温度不均匀度越大，也需在热加载设计时予以关注。 |

| The work aims to investigate the impact of self-rotational effects on the internal flow and heat transfer characteristics of a heating device under global and local heating conditions, so as to guide the engineering design of heating devices for environmental testing. Through numerical simulations, the distribution characteristics of the velocity and temperature fields within a self-rotating heating device under actual global and local heating conditions were examined, along with the average heat transfer performance of the heating wall. The impact of rotational effects on key technical indicators of the heating device, such as the temperature rise rate, target equilibrium temperature, and temperature non-uniformity, was analyzed. The flow velocity within the device initially weakened and then strengthened with the increasing rotational effects. At a rotation speed of 1 000 r/min, the internal air flow was suppressed by the rotational effect, while at the speed exceeding 1 000 r/min, the rotational effect promoted the internal air flow. Under global heating conditions, the temperature rise rate of the heating device ranged from 20.92 K/s to 34.43 K/s for the rotation speed ranging from 0 r/min to 10 000 r/min. The internal equilibrium temperature initially increased and then slightly decreased with the increasing rotation speed. Under local heating conditions, the temperature rise rate ranged from 3.47 K/s to 4.49 K/s, with the highest internal equilibrium temperature observed at 1 000 r/min. The temperature non-uniformity within the device became more complex due to uneven heating of the sidewalls. The design of heating devices must fully consider the impact of rotation speed on the temperature rise rate and equilibrium temperature. Additionally, larger heating areas lead to greater temperature non-uniformity within the device, which should also be addressed in the design process. |
