论文摘要
研究了流向黑洞的测试液的积聚。特别是，通过采用动态的哈密顿方法，我们能够找到各种在保形重力中的黑洞的关键点。在这些情况下，我们已经分析了采用等温州方程的积聚解决方案。已经考虑了不同测试液在共形重力黑洞上的稳态和球面对称积聚。此外，我们在状态方程和保形重力黑洞的情况下对这些流进行了分类。在黑洞的所有三个情况下，还讨论了多面体流体积聚的新行为。黑洞质量积聚率是这项研究中最重要的部分，在该研究中，我们已经研究了Schwarzschild黑洞会产生典型的特征，而不是保形重力黑洞和Schwarzschild De-Sitter De-Sitter Black Black Hole。临界流体流量和质量积聚速率已通过影响参数$β$，$γ$，$ k $以图形方式呈现，并且这些参数具有重要意义。此外，这些区域之间的最大积聚质量率落在通用范围内和杀戮视野附近，最小积聚率发生。最后，将结果与文献中可用的黑洞的不同情况进行了比较。
The accretion of test fluids flowing onto a black hole is investigated. Particularly, by adopting a dynamical Hamiltonian approach, we are capable to find the critical points for various cases of black hole in conformal gravity. In these cases, we have analyzed the general solutions of accretion employing the isothermal equations of state. The steady state and spherically symmetric accretion of different test fluids onto the conformal gravity black hole has been considered. Further, we have classified these flows in the context of equations of state and the cases of conformal gravity black hole. The new behavior of polytropic fluid accretion is also discussed in all three cases of black hole. Black hole mass accretion rate is the most important part of this research in which we have investigated that the Schwarzschild black hole produce a typical signature than the conformal gravity black hole and Schwarzschild de-Sitter black hole. The critical fluid flow and the mass accretion rate have been presented graphically by the impact parameters $β$, $γ$, $k$ and these parameters have great significance. Additionally, the maximum mass rate of accretion fall near the universal and Killing horizons and minimum rate of accretion occurs in between these regions. Finally, the results are compared with the different cases of black hole available in the literature.
