    In this paper, we used the more rigorous general relativistic viscose hydrodynami-cal equation to discuss and calculate the temperature profile in the accretion disk around a Kerr black hole. We argued that in the accretion disk around a black hole, it is significant in principle for considering the release of the internal energy of the accreting materials. Taking the effect of internal energy of the accreting materials into account and using the classical theory, we have shown that the occurrence of solution...

    In this paper, we used the more rigorous general relativistic viscose hydrodynami-cal equation to discuss and calculate the temperature profile in the accretion disk around a Kerr black hole. We argued that in the accretion disk around a black hole, it is significant in principle for considering the release of the internal energy of the accreting materials. Taking the effect of internal energy of the accreting materials into account and using the classical theory, we have shown that the occurrence of solution of the abnormal temperature profile around a Schwarzschild black hole is possible. In this consistent solution, the temperature profile are not always monotonic, i.e. the temperature is not always a monotonic descending function of the raduis r, not as that of the usual case, but there exists probably a temperature profile with maximum at the certian raduis, in consequence it is existed a cooling region.In order to discuss this subject further, it is natural logically development to using the more rigorous relativistic hydrodynamical equation. Therefore, we will follow the general methods by Bardeen, J. M., Press, W. H., Teukolsky, S. A., and Novikov, I. D.. Thome, K. S. et al. to establish a possible model of accretion disk for the Kerr black hole. Our fundamental assumptions are: (1) The central plane of the disk coincides with the equatorial plane of the black hole. The disk is a perfectly aixal-symmtrie and is thin; (2) The orbital motions of the materials in the disk are controled mainly by the gravitational pull of the hole so that the orbits are very nearly geodesic, while the component of the velocity in the radial direction is very small and the motions in the direction normal to the disk may be neglected; (3) The dominate pressure is the gas pressure, but the radiative pressure is negligble; (4) The radial heat transfer is very small in comparison with the energy radiated from the surface of the disk; (5) The internal energy of the accreting materials in the disk must be calculated. Under these assumptions, our main conclusions obtained are: (1) If the radiative mechanism of the materials in the disk is the black-body radiation, the result is coincidence with the classical theory, whatever kind of the viscose law be; (2) For free-free radiation, the temperature profile is in substance just like the classical case. Thus it is further demonstrated theoretically that there exists indeed such a possible accretion disk around the Kerr black hole which has a fast cooling ring region just laid inside the temperature maximum as its main character. In this cooling ring region, there are probably some pecularities which have not existed for the usual temperature profile.

    本文采用较严格的广义相对论粘滞流体动力学方程,讨论并计算了在Kerr度规下黑洞吸积盘的温度分布问题.结果表明,对于绕Kerr黑洞的吸积盘,温度确有极大值的分布轮廓.而且,当盘内物质的辐射机制是黑体辐射时,不论粘滞机制属于何种类型,结果都一样;对于自由—自由辐射,采用a粘滞律模型,与我们在文[1]中所得的结果十分类似.这表明文[1]中所取的近似足合适的.计算还表明,在温度极大值所处半径的内面,有一迅速冷却的环状区域存在.在这一环状区域内,有可能具有某些在通常温度分布时所没有的特性.

    For the calculation of temperature field of turbine disks by finite elemeat method, it is generally necessary to give some boundary conditions before the calculation can be performed. Thus,it periotsly meels some ecperiento on coonntitions. Sail experiment is known to be very expensive, and precomputed boundary conditions are usually not satisfactory for our purpose. In particular a jet engine in the phase of design or development or a turbine disk whose temperature field requires to be readjusted, the associated boundary conditions cannot be given. This paper has established the direct relationship between the temperature field and operating conditions, and then the above-mentioned difficulties are avoidable. This makes the calculation of the temperature field of turbine disks more rational and quite convenient. A computation example is also presented in this paper.

    通常,为了用有限元素法计算涡轮盘的温度场,必须予先给出三类边界条件。为此,要事先进行必要的试验或计算,显然试验工作要化费大量的资金,而计算所得之边界条件往往不能满足实际计算的需要。尤其对于设计中的发动机,或拟调整温度场之涡轮盘,往往不能给出有关的边界条件。本文建立了涡轮盘温度场与其工作条件的直接联系,从而避免出现上述困难,使涡轮盘温度场的计算更加合理和便利。本文并提供了一个计算实例。
