A comparative assessment of the prediction capability of transitional turbulence models was carried out in the chord Reynolds number range $R{e}_c=2.3\times 10^4-2\times 10^5$ with the NACA 0012 and NACA 4415 airfoils. Four transition models based on the $k-\omega$ framework, i.e., the low-Reynolds number correction, $R{e}_{\theta }-\gamma$, $\gamma$ and $k-k_l-\omega$ were chosen to simulate the flow and aerodynamic characteristics. It is found that the prediction capability of a model is related to the nature of the flow structure and affected by the $R{e}_c$ and angle of attack ($AOA$). Among all the models, the $R{e}_{\theta }-\gamma$ model has the best prediction capability and is recommended for low $R{e}_c$ applications such as small wind turbines. The $k-k_l-\omega$ model has the secondary capability for some $R{e}_c$ and low $AOAs$. The $\gamma$ model has a similar frame to the $R{e}_{\theta }-\gamma$ model but cannot reliably predict the flow at larger $AOAs$ and lower $R{e}_c$. The low-Reynolds number correction model is not recommended for the low $R{e}_c$ range.
