AERODYNAMIC INVESTIGATION OF A 2D AIRFOIL IN GROUND EFFECT ABOVE WATER USING OPENFOAM
Based on the OpenFOAM two-phase flow solver,the ground effect of a two-dimensional airfoil above the water surface is studied.The ground effect is intense during the surface taxiing of a seaplane.In order to verify the adaptability of OpenFOAM to this type of problem,the aerodynamic calculation of a simple two-dimensional airfoil above the water surface is investigated.Considering the subsequent need to simultaneously study the two-phase flow of water and gas,the interFoam solver is specifically used to calculate the problem.And both the results of the single-phase and twophase flow calculation are compared with the experimental data as well.The results show that the ground effect will induce the separation of the airfoil upper wing surface.And also the two-phase flow calculation results of OpenFOAM are different from those of the single-phase flow calculation,but the magnitude of the difference is not very significant in a strong ground effect area close to the water surface.
