The results show that the error between the experimental data and the numerical simulation results increases with the increase of scaling factor, and the smaller the scaling factor, the smaller the error. Therefore, when conducting experiments, it is necessary to consider scaling down the experimental model to improve the accuracy of the experimental results.
