论文摘要
观察结果和数值模拟表明，流出过程中通常存在流出过程。我们通过包括流出的作用来重新审视黑洞积聚流的热平衡解决方案。我们的研究重点是将流出的冷却速率与对流的比较。我们的结果表明，除了内部区域外，流出可以主导在广泛的流程中，这与先前的数值模拟非常吻合。我们认为，以对流为主的内部区域以及流出为主导的外部区域应该是超级 - 埃德丁顿积聚流量和低吸积率的光学薄流的一般径向分布。
Observations and numerical simulations have shown that outflows generally exist in the accretion process. We revisit the thermal equilibrium solutions of black hole accretion flows by including the role of outflows. Our study focuses on the comparison of the cooling rate of outflows with that of advection. Our results show that, except for the inner region, outflows can dominate over advection in a wide range of the flow, which is in good agreement with previous numerical simulations. We argue that an advection-dominated inner region together with an outflow-dominated outer region should be a general radial distribution for both super-Eddington accretion flows and optically thin flows with low accretion rates.
