The Performance Enhancement of Axial Flow Turbine Using Numerical Technique

This paper aims to study the performance enhancement of subsonic axial flow turbine using numerical technique. R123 Organic Rankine Cycle (ORC) with high density is considered as the working fluid. A single stage axial flow turbine consisting of stator and rotor is used to carry out the analysis. The numerical analysis is carried out using ANSYS R18.1 version. The parameters considered to design the turbine geometry are tip diameter, hub diameter, blade height, half wedge angle of leading and trailing edge and number of blades of the stator and rotor. The design and study of axial flow turbine is mainly focused for engineers and technical researchers working in the field of ORC and engine design. Grid independence test performed with different mesh size to keep the computational economy intact. The experimental results are later compared with the theoretical calculation for verification.
