Description Condensing type geothermal turbine is a mechanical device that used to convert thermal energy into mechanical energy, then after converted to electrical energy in the generator by the rotation of the rotor’s magnetic field. Development of blade material for geothermal turbine application which using local content is crucial due to the blade’s turbine are 100% imported. So, efforts to produce blade material with high local content are very strategic to support national energy independence in the future. The Agency for the Assessment and Application of Technology (BPPT) started from 2020 until 2023 will focus on the development of the blade material for geothermal turbine application. As a starting point of the research, modelling and virtual testing of the stage-1 blade turbine were performed. In this study, the model is done in CATIAV5 software. Solid model is then imported to ANSYS workbench 15.0. Thermal-Structural analysis of turbine blade using the Stainless steel-based alloy with the ANSYS workbench 15.0 was carried out. In the thermal analysis, the model is given temperature, convective heat flux transfer coefficient and atmosphere gas temperature and then is solved for the heat flux distribution over the blade surface. The obtained heat flux distribution is taken as the thermal load into the Static structural analysis. In the static structural, the obtained model is given structural load, namely centrifugal force. The model is then conducted virtual testing in order to obtain stresses and deflections. The results showed that the model of stage one blade turbine is safe when operating at the determined loads.
