Abstract

This paper presents a methodology for numerical simulation of a CA9 rotor Wells turbine. The work was carried out for a turbine size of 0.6m in diameter and computation were done at Re = 5 × 10⁵, Ma = 0.2 and solidity of 0.48 (6 blades) over a range of flow rates. The aim of this work was to benchmark Computational Fluid Dynamics (CFD) and predict the turbine performance and investigate the aerodynamic characteristics of the CA9 blade profile. Results show that reasonable agreement with experimental data can be achieved. Difficulty to predict drag accurately in stall region was also experienced. A maximum efficiency of 69% was computed and flow separation was found to start from the tip trailing edge.
