A methodology for modelling the vertical-axis turbine intwo-dimensional (2D) basedon the theory of actuator cylinder model

Abstract

Turbines are the most common devices used in the field of wind energy and tidal energy. They are also the main research objectives of scientists worldwide. Different research methods areapplied to study these devices, including the numerical simulation method. This is an advanced approach that helps to save costs of calculation,but it still keeps the accuracy. In the numerical simulation method, building and selecting a suitable model as well as ensuring the high accuracy of the model is essential. It helps to determine the success of the research method. The article presents the results of the research and development of a methodology to model the vertical axis turbine in 2D dimension based on the theory of the Actuator Cylinder model combined with the use of the Navier-Stokes equations and standard k-ε turbulence model applied in the ANSYS FLUENT software. The lift force (normal force) and drag force (tangential force) acting on the turbine blades are compared with experimental results to verify the model's reliability. Additionally, the simulation results are compared with those obtained from Strickland's theoretical model, further highlighting the accuracy of the research. The research results demonstrate a strong correlation between the numerical simulation model and the experimental dat
