Abstract
The disclosed invention relates to coolant flow control apparatus for rotating heat exchangers such as used with a liquid cooled turbine blade and disc. By employing a combination of inlet and outlet orifices in the constrained coolant path of the apparatus, the liquid coolant can be made to rapidly reach and maintain supercritical temperature and pressure in the heat exchanger over a range of coolant heat absorption rates.
