Joukowski Simulator is an Android app that utilizes the theory of complex analysis to calculate flow-fields and aerodynamics in potential flow scenarios. Specifically, it focuses on the flow around a Karman-Trefftz airfoil or circular cylinder. This app is a valuable tool for those interested in understanding potential flows, conformal mappings, and the impact of airfoil geometry and flow parameters on velocity field patterns and surface pressure distributions.

One of the key features of Joukowski Simulator is its interactive generation and visualization of potential flow around a Karman-Trefftz airfoil or circular cylinder. Users can explore different scenarios and observe the corresponding flow patterns. Additionally, the app provides interactive calculations and plotting of surface pressure distribution, allowing for a comprehensive analysis of aerodynamics.

Joukowski Simulator also offers the functionality to export and share the results in MATLAB/Octave, Python, or CSV formats. This includes velocity fields, airfoil coordinates, Cp distribution on the airfoil's surface, as well as potential and streamfunction fields. The app even provides MATLAB or Python commands to assist users in quickly plotting the results in their preferred environment.

Overall, Joukowski Simulator is a valuable educational tool for those looking to delve into the subject of potential flows and conformal mappings. It provides an intuitive interface and comprehensive features that allow for a detailed analysis of aerodynamics in potential flow scenarios.
