A multi-fidelity surrogate model based on data extension using POD and ANN is proposed. The model can fuse various-fidelity heterogeneous data through the extension model, and provide accurate predictions of the flow data. The case of airfoil validated the proposed method, and indicates that it can significantly improve modeling efficiency with good precision.
