Numerical simulations of the single rotor blade row with multi stage tip turbine were conducted to investigate a dependency of enthalpy drop on a bulkhead positioning of the tip turbine. When leading edge of a rotor blade comes close to a stator blade which separates inlets of high pressure turbine (HPT) and low pressure turbine (LPT), a bulkhead which separate outlets of HPT and LPT should be placed with distance 2L toward the rotation direction of the rotor from the trailing edge of that rotor blade, where multiplication of a rotor speed U and mean blade passing time T of fluid led from HPT stator makes L. If the bulkhead is placed appropriately as mentioned above, the enthalpy drop of the tip turbine increases at a border where the turbine rotor blades proceed from LPT to HPT with time. While at a border where the turbine rotor blades proceed from HPT to LPT with time, the displacement of bulkhead should be zero instead of the 2L.
