Airfoil Simulation in Potential Flow

To better understand airfoil performance, simulation in potential flow can be implemented to obtain data such as pressure coefficient distribution and lift coefficient. The simulation typically involves solving Laplace's equation for the velocity potential using boundary element methods or panel methods, where the airfoil surface is discretized into panels with singularity distributions. Different factors can be considered in the simulation, including airfoil geometry specifications, aerodynamic parameters, and flight velocity conditions. Multiple iteration optimizations can be performed using gradient-based algorithms or evolutionary optimization techniques to achieve optimal airfoil design. Furthermore, experimental data can be integrated through validation functions and correction algorithms to verify and refine simulation results, thereby further enhancing airfoil performance and stability. The implementation typically involves calculating flow tangency conditions using the Neumann boundary condition and computing pressure coefficients through Bernoulli's equation applied to the velocity field solution.
