反常粘滞吸积薄盘的稳定结构

根据描述吸积盘的流体动力学方程,给出无磁场情况下的质量、动量和能量守恒方程。在所给定方程的基础上,利用新的反常粘滞计算了黑洞周围吸积盘内区的结构。数值结果表明盘内区的气体不是做开普勒旋转,温度随吸积率变化比较明显,在M=10M_⊙,M ^.=100M ^._E的情况下,吸积盘的最大温度可达到3.35×10⁷K。 同时文中也给出了面密度和径向速度的分布规律。

The stationary structure of the thin accretion disk with anomalous viscosity

Based on the hydrodynamic equations of accretion disks,the conservation equations of mass,momentum and energy with absence of magnetic field were given.On the basis of the equations obtained,the structure of the inner region of the accretion disks surrounding black hole was calculated by using the new anomalous viscosity.The numerical results showed that the gas motion was not Keplerian in the inner region of the disk.The temperature varied significantly with the accretion rate,and the maximal temperature o...
