The development of a closed cycle gas turbine with super-critical carbon dioxide as a working fluid is under way in order to generate power from waste heat source of a low or intermediate temperature range from industry. Its demonstration test using a reduced scale turbomachine is under way. Principal specifications follow; net power output of 10kWe and recirculation CO_2 flow rate of 1.2kg/s under the given turbine inlet conditions of 550K and 12MPa respectively. Preliminary test results on the measurements of compressor required work is presented. Specific work input to compressor was measured and compared with analysis model that the specific work input is proportional to the value of compressibility coefficient at inlet to compressor. The model is proved to be valid.
