Expander Modelling in Binary Cycle Utilizing Geothermal Resources for Generating Green Energy in Victoria, Australia

This paper investigates the computational modeling of a binary organic Rankine power cycle. The computer model has been generated to aid the design and manufacture of apparatus that will be utilized during experimentation on the geothermal resources in Victoria, Australia. A review of Australia's geothermal prospects is also presented here. Suitable technology to utilize the low grade heat from the available geo-fluids has been explained to connect the recent technology with the new approached design. The paper involves the design of the heat engine with the reaction turbine. In addition, theoretical analysis and performance predictions have been presented briefly in the paper to compare between different diameters for the reaction turbine in the organic Rankine cycle engine with power and efficiency. In this paper, realistic recommendations will be discussed to the best of the geothermal energy as sustainable energy resources to be useful for achieving the Australian target.The binary cycle is modeled to evaluate the output power and the efficiency. A computer model for binary cycle is presented in this paper. Thermal-mechanical energy conversion efficiency is predicted using the computer modeling and presented in the analysis.
