ABSTRACT

This paper constructs a Partially-Averaged Navier-Stokes (PANS) turbulence model using User-Defined Function (UDF) programming based on FLUENT software and applies it to the numerical simulation study of the NACA2415 airfoil. Through the secondary development of FLUENT, the construction and validation of the PANS model were successfully achieved. The flow field characteristics of the NACA2415 airfoil at different angles of attack were calculated, and the lift coefficient was monitored and compared with wind tunnel experimental results. The study showed that the PANS model effectively captures the velocity streamlines and pressure variations on the surface of the airfoil, demonstrating a high predictive accuracy compared to experimental data. This research provides a technical reference for the simulation of complex flow fields and the optimization of turbulence modeling methods.
