Abstract The matter accretion onto a noncommutative (NC) inspired Schwarzschild black hole is addressed for a polytropic fluid and results are compared with Schwarzschild black hole. The flow parameters - critical velocity u(r), sonic speed c s 2 and accretion rate M ˙ are derived from the NC static black hole and are related to the outcomes acquired for the standard Schwarzschild black hole. Due to the effect of noncommutative parameter θ, the mass accretion rate decreases with the increase of the strength of θ and vice versa. The same effect is seen for the sound speed and fluid velocity. The fluid velocity is positive as well as negative for the NC black hole corresponding to Schwarzschild black hole. The role performed by θ is significant in order to acquire the lager accretion rate for NC black hole than the Schwarzschild black hole.

米歇尔吸积到非交换黑洞

摘要 针对多变流体解决了受非对易 (NC) 启发的 Schwarzschild 黑洞的物质吸积问题，并将结果与​​ Schwarzschild 黑洞进行了比较。流动参数 - 临界速度 u(r)、声速 cs 2 和吸积率 M 来自 NC 静态黑洞，并且与标准 Schwarzschild 黑洞获得的结果有关。由于非对易参数 θ 的影响，质量吸积率随着 θ 强度的增加而减小，反之亦然。对于声速和流体速度可以看到相同的效果。对应于 Schwarzschild 黑洞的 NC 黑洞的流体速度为正值和负值。θ 的作用对于获得比史瓦西黑洞更大的 NC 黑洞吸积率是很重要的。
