The results generated by various pretrained models demonstrate that transfer learning yields a comparable accuracy from a reduced training time. Furthermore, the models are pretrained through transfer learning on large-scale datasets and fine-tuned on small datasets to improve their generalizability in engineering applications. This results in the maximum error that is typically observed near the shock area decreasing by 50%. LaSalle modification of the S1223 to S1223RTL Max thickness 13.5 at 19.9 chord Max camber 8.3 at 55.2 chord Source UIUC Airfoil Coordinates. The dat file data can either be loaded from the airfoil database or your own airfoils which can be entered here and they will appear in the list of airfoils in the form below.

To increase accuracy near the shock area, multilevel wavelet transformation and gradient distribution losses are introduced into the loss function. Plot and print the shape of an airfoil (aerofoil) for your specific chord width and transformation. The statistical results show that these methods generate accurate predictions over the complete flow field, with a mean absolute error on the order of 1 × 10 −4. In addition, four methods are designed to encode the geometric input with various information points and the performances of these methods are compared. In this study, a modified vision transformer-based encoder–decoder network is designed for the prediction of transonic flow over supercritical airfoils. Although deep-learning methods can effectively predict flow fields, the accuracy of these predictions near sensitive regions and their generalizability to large-scale datasets in engineering applications must be enhanced. The Reynolds-averaged Navier–Stokes equation for compressible flow over supercritical airfoils under various flow conditions must be rapidly and accurately solved to shorten design cycles for such airfoils.
