We study the ejection of winds from thin accretion discs around stellar mass black holes and the time evolution of these winds in presence of radiation field generated by the accretion disc. Winds are produced by radiation, thermal pressure and the centrifugal force of the disc. The winds are found to be mildly relativistic, with speeds reaching up to terminal speeds $0.1$ for accretion rate $4$ in Eddington units. We show that the ejected matter gets its rotation by transporting angular momentum from the disc to the wind. We also show that the radiation drag affects the accretion disc winds in a very significant manner. Not only that the terminal speeds are reduced by an order of magnitude due to radiation drag, but we also show that the non-linear effect of radiation drag, can mitigate the formation of the winds from the matter ejected by the accretion disc. As radiation drag reduces the velocity of the wind, the mass outflow rate is reduced in its presence as well.

来自开普勒圆盘的辐射驱动风的模拟

我们研究了从恒星质量黑洞周围的薄吸积盘中喷射出的风，以及在吸积盘产生的辐射场存在的情况下这些风的时间演化。风是由辐射、热压和圆盘的离心力产生的。发现风具有轻微的相对论性，在爱丁顿单位中，风速达到终端速度 0.1 美元，吸积率 4 美元。我们表明，喷射出的物质通过将角动量从圆盘传输到风来获得旋转。我们还表明辐射阻力以非常显着的方式影响吸积盘风。不仅终端速度由于辐射阻力降低了一个数量级，而且我们还表明辐射阻力的非线性效应，可以减轻由吸积盘喷出的物质形成的风。由于辐射阻力降低了风速，因此质量流出率在其存在时也会降低。
