ABSTRACT
The article discusses a research study on verifying the computational fluid dynamics (CFD) solver in the National Advisory Committee for Aeronautics (NACA) 0015 Airfoil focused on the lift and drag forces and pressure distribution by observing the Wing-in-Ground-effect (WIG). Researchers considered changes in ground clearance and angle attack from 0 degrees to 10 degrees and used the Semi-implicit Method for Pressure-Linked Equations (SIMPLE) algorithm to solve the problem of high angles of attack making adverse pressure that can cause turbulent behavior. It cites the use of the second-order upwind and Quick sorting algorithm for verifying viscosity of turbulence and momentum. Results for different models showed accurate results in the Spalart-Allmaras method.
