title = "Aerodynamics of a transonic airfoil above wavy ground",
abstract = "The Wing in Ground Effect (WIG) aircraft usually operates near water surface to avoid obstacles. The water surface is often not flat. However, the experiment on a non-flat surface is difficult to conduct, while the numerical simulation can easily study the influence of the wavy ground. There are very few archived papers that address this problem. To increase the traffic volume of the WIG aircraft, one possible way is to increase the flight speed, which can result in transonic flow near the ground. Currently the studies on transonic flight in ground effect are also very few. The goal of this research is to study the aerodynamics and flow physics of a typical transonic RAE2822 airfoil at angles of attack (AOA) from 0 to 4 deg. and Mach numbers from 0.5 to 0.8 in the presence of a wavy ground by varying the ground height. The compressible Reynolds-Averaged Navier-Stokes equations with Spalart-Allmaras (SA) turbulence model are solved using the commercial CFD solver ANSYS FLUENT to study the aerodynamics of a transonic airfoil above wavy ground.",
