Numerical simulation of a horizontal axis tidal turbine with a pre-swirl stator

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Pre-swirl stator concept is proposed in this paper to improve the overall efficiency of Horizontal Axis Tidal Turbine (HATT). Numerical simulation of HATT with and without pre-swirl stator concept is conducted in different Tip Speed Ratio (TSR). A three bladed tidal turbine is numerically modelled and solved by a three-dimensional finite volume solver. Turbine model is studied using a timeaccurate Reynolds-Averaged Navier-Stokes (RANS). The transient rotor-stator model with sliding mesh technique is used. The power coefficients of a HATT without pre-swirl stator are predicted numerically and validated by existing experimental data. It has been found that the use of pre-swirl stator can improve the velocity field around the turbine leading to an increase of the overall turbine efficiency by about 13% in specific TSR.
