Master's Thesis from the year 2008 in the subject Engineering - Aerospace Technology, grade: A, University of Southampton, course: Computational Aerodynamics, language: English, abstract: Wing-in-ground effect (WIG) vehicles offer an exciting capability to fill the enormousvoid between speed of an aircraft and the payload capacity of a ship. WIG vehicleswould be able to move cargo and passengers faster than a ship and more economicalthan an aircraft. Ground effect is a phenomenon that occurs on all wings flying closeto the ground or a surface.The aim of this project is to investigate the behavior of wings (NACA/DHMTU series)in ground effect (on a fixed/variable terrain) using Fluent CFD package. The NACA0012 and DHMTU series used in this project are designed specifically to fly in closeproximity to the ground.The performance of the NACA/ DHMTU airfoils is examined for the lift and the dragcoefficients at different altitudes with varying angle of attack. The results arecompared to experimental data that is available to assess the accuracy of the CFDsimulation.
