TESLA-TYPE TURBINE, METHOD FOR OPERATING A TESLA-TYPE TURBINE, APPARATUS FOR CONVERTING THERMAL ENERGY INTO MECHANICAL ENERGY, METHOD FOR CONVERTING THERMAL ENERGY INTO MECHANICAL ENERGY AND METHOD FOR CONVERTING THERMAL ENERGY INTO ELECTRICAL ENERGY

摘要

The invention relates to a Tesla-type turbine (10) for converting the enthalpy of a gas volume flow (17) into mechanical energy, and to a method for operating the Tesla-type turbine (10) according to the invention. The invention further relates to an apparatus for converting thermal energy into mechanical energy, a method for converting thermal energy into mechanical energy, and a method for converting thermal energy into electrical energy. The Tesla-type turbine (10) comprises at least one disc (11) which is positioned on an axis of rotation (50) and which can be set into rotation by a gas volume flow (17) flowing substantially tangentially, so that mechanical energy can be collected at a shaft (51) coupled to the disc (11). A disc body (13) that forms the disc (11) has at least one cavity (14) in which, for the purpose of cooling the disc body (13), a cooling medium (16), in particular a cooling liquid, is received or can be received. The Tesla-type turbine (10) also has at least one gas receiving chamber (12) for receiving and discharging the gas volume flow (17) flowing at least partly tangentially relative to the disc (11).
