我们计算了活动星系核(AGN)中遮挡环流出的一系列模型。我们的模型假定旋转支承的环面被来自内部吸积盘和黑洞的强烈X射线照射和加热。由于这样的加热，在我们的模拟中观察到了强烈的双锥形外流。我们计算了三维流体力学模型，假设了轴对称，并考虑了X射线加热、电离和辐射压力的影响。我们讨论了这一大类模型的行为，它们的速度场、质量通量和温度，作为环面性质和X射线通量的函数。在假定纯吸收的情况下，对样品模型在不同倾角和观测时间下的合成热吸收光谱进行了计算。结果表明，这些模型的质量通量和流速可与Seyfert-1热吸收体的观测结果相媲美，并能产生丰富的吸收线谱。
We have calculated a series of models of outflows from the obscuring torus in active galactic nuclei (AGNs). Our modeling assumes that the inner face of a rotationally supported torus is illuminated and heated by the intense X-rays from the inner accretion disk and black hole. As a result of such heating, a strong biconical outflow is observed in our simulations. We calculate three-dimensional hydrodynamical models, assuming axial symmetry and including the effects of X-ray heating, ionization, and radiation pressure. We discuss the behavior of a large family of these models, their velocity fields, mass fluxes, and temperature, as functions of the torus properties and X-ray flux. Synthetic warm- absorber spectra are calculated, assuming pure absorption, for sample models at various inclination angles and observing times. We show that these models have mass fluxes and flow speeds comparable to those inferred from observations of Seyfert 1 warm absorbers, and that they can produce rich absorption-line spectra.
