MultiElement Airfoils 3.0 is based on a novel cartesian grid generation procedure for solving the two-dimensional axisymmetric Euler Equations. The software can be used to efficiently analyze subsonic, transonic and supersonic flows past multiple airfoils placed at arbitrary locations.
The Euler solver is optimized for the cartesian grid scheme and is used to compute the lift and drag coefficients for rotor craft sections, high speed race car wings and transonic aircraft wing sections. It can also be used compute the drag divergent Mach number (Mdd) for multiple airfoil configurations. This is especially useful for conceptual design of rotor blades and business jet aircraft.
Results are comparable to body-fitted grid solutions. For example, the computed lift and wave drag coefficients for a NACA 0012 airfoil at one degree angle of attack and Mach number of 0.85 is found to be 0.365 and 0.0591, respectively. These numbers are within 2% of the numbers found in the literature for the same case.
