We produce radiation hydrodynamics models of an AGN 'torus' plus outflow on 1-100 pc scales. This large scale permits direct comparison with observations, provides justification for configurations used in radiation transfer models, and tests the sensitivity of results of smaller scale dynamical models. We find that anisotropic radiation from an AGN accretion disk can cause an outflow to evolve to become more polar, agreeing with the ubiquity of polar extended mid-IR emission, and the general geometry predicted by radiative transfer models. We also find the velocity maps can reproduce many features of observations, including apparent 'counter-rotation'.

活动星系核的辐射流体动力学模型：超越中央秒差距

我们以 1-100 pc 的比例生成 AGN“环面”外流的辐射流体动力学模型。这种大尺度允许与观测直接比较，为辐射传递模型中使用的配置提供理由，并测试小尺度动力学模型结果的敏感性。我们发现来自 AGN 吸积盘的各向异性辐射会导致外流演化为更具极性，这与普遍存在的极地扩展中红外发射以及辐射传递模型预测的一般几何形状一致。我们还发现速度图可以再现观察的许多特征，包括明显的“反向旋转”。
