Abstract: The performance of steam turbine blade is related to many factors. One of the important factors is the degradation and change in turbine blade profile after many hours of operation. This leads to increased in flow losses and hence reduction in overall turbine efficiency. The performance of turbine blade can be predicted and improved by using Computational Fluid Dynamics (CFD). CFD is the art of numerically solving the governing fluid flow equations in order to obtain the descriptions of the complete flow-field of interest. With the availability of computer power and efficient numerical algorithm, CFD is becoming a very important tool for engineers in improving the performance of component involving fluid flows. The reason is that CFD effectively replace the needs to perform expensive experimental measurement and testing of new design and prototype. To develop better performing blades, it is essential to identify the losses generating mechanism and study their influence and effects on performance. This paper outlines design considerations and the estimation of efficiency of LP Steam Turbine using CFD, thus aiding in optimizing the design and helps in integrating CFD into the design process itself. The CFD results are in concurrence with the analytical values.
