In the 1st report, numerical results were presented for the swirling flow field in a rotating hollow turbine shaft. The existence of a rotating spiral vortex at the place where the swirling flow turns radially outward was shown. The first non-axisymmetric mode of a single spiral vortex was transformed into the second mode of a double sprial vortex at a specific rotating speed of the shaft. In this report, the downstream region of the computational domain is extended to the wheel space, the cavity between the corotating turbine disks, to solve the swirling flow field in the internal cooling air system of a gas turbine. The data on precessing frequencies of the rotating spiral vortex in this numerical analysis are compared with experimental results in a companion paper(3rd report). In addition, attention is paid to the three-dimensional swirling flow field in the rotating cavity with the rotating spiral vortex in the straigth tube.
