Abstract: The Beddoes-Leishman model (B-L model) was widely applied in the airfoil's dynamic loads prediction. But the need for numerous experimental parameters greatly limits its application range. In this study, numerical simulation was used to simulate the wind tunnel experiments of airfoils to obtain the required parameters. Take the S809 and NACA0012 airfoils as examples, Fluent software was used to calculate the static parameters, and dynamic mesh technology was used to simulate the sinusoidal oscillation wind tunnel experiments of airfoils to obtain the dynamic parameters. Use the modified B-L model with the obtained parameters to predict the dynamic stall characteristics of the airfoils. The predicted results are in good agreement with the experimental data of the wind tunnel, which means that it is promising to use numerical simulation to calculate the parameters required by the B-L model to predict the dynamic stall characteristics of an airfoil. It provides a simpler and more feasible method for predicting the dynamic loads of the blade of wind turbines and tidal current turbines.
