Abstract
This study aims to investigate the aerodynamic analysis of a Darrieus-type vertical axis
wind turbine (VAWT) using the Lattice Boltzmann Method (LBM). The objective is to assess the
accuracy and performance of the meshless LBM approach in predicting torque coefficients, velocity,
turbulence intensity, and vorticity distributions for VAWT aerodynamic analysis. Two turbulence
modelling approaches, Large Eddy Simulation (LES) and Reynolds-Averaged Navier-Stokes (RANS),
are employed to model the flow domain. The central problem revolves around comparing the
performance of different turbulence models based on their agreement with experimental results for
power and torque coefficients. The findings demonstrate the effectiveness of the WALE turbulence
model in achieving the best agreement with experimental data. Overall, the study provides valuable
insights into applying LBM in VAWT aerodynamic analysis and highlights the advantages of the
meshless approach compared to traditional CFD methods.
