The effects of internal heat leakage intensifies with increasing the pressure ratio. Internal heat leakage should be considered at the pressure ratio higher than 5. Internal heat leakage inside the impeller reduces the impeller maximum temperature. Heat leakage inside the casing degrades the compressor performance.
