Instead of lubrication oil, the test machine is fed with a high-temperature oily working medium liquid for the lubricant. This idea is proposed in order to omit the lubricationpump. By feeding of the oily working medium liquid lubricant, the working fluid must be of low quality (dryness fraction). For the calculation of wet expansion, we introduce the actual adiabatic expansion with thermophysical properties of the actual working medium. This expansion is the isentropic expansion in which the adiabatic exponent χ is variable. The calculated values of this method give fairly good agreement with the experimental results. In this paper, as the result of the calculation and experimentation, we report the performance characteristics of a small-size screw expander operated with a low-quality (χ=0.6～1.0) actual working medium.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"日本機械学會論文集.
