Convergence and Accuracy of Potential-Flow Methods

What is it about?

In the early 1900s simple, vortex-based models were developed for airplane wing design. One of the questions discussed here is why these methods were successful. The second topic discussed is aimed at highlighting the differences between ideal flow models and current numerical solutions, in terms of methodology and grid sensitivity. The point in this whole discussion is that without those early classical models, novice engineers using CFD may end upon with the wrong results.
