Abstract: A turbine arrangement includes a turbine rotor arrangement, a turbine seal arrangement and a turbine outlet stator vane arrangement. Turbine rotor arrangement includes a rotor and a plurality of turbine blades that extend radially. Each turbine blade has a turbine shroud. Turbine seal arrangement is spaced radially around the turbine shrouds. Turbine outlet stator vane arrangement includes radially inner and outer annular members arranged coaxially and a plurality of vanes extending radially between the radially inner and outer annular members. The vanes are arranged downstream of the turbine blades. Liner is spaced radially inwardly from a radially inner surface of the annular member to define a chamber. Turbine shrouds and the upstream end of the liner are arranged such that in operation any leakage flow of gas between the turbine shrouds and the turbine seal arrangement flows into the chamber to manage the temperature of the radially outer annular member.
