Abstract

Based on geometry and design parameters of "diamond back" wing, influence of vertical height difference of the anterior and posterior wing aerodynamic characteristics at low Reynolds number were simulated by two-dimensional computational model which use NACA6411 airfoil. The simulation results indicate that the Transition SST turbulence model high accuracy and creditability in solving flowing around an airfoil at low Reynolds number; Near the station of leading edge distance between the anterior and posterior wing is about 1.5 times that of chord length of anterior airfoil, the influence of vertical height difference aerodynamic characteristics appear the phenomenon that change trend reversal; One of effective optimization methods for “diamond back" aerodynamic configuration is designing the vertical height difference and the leading edge distance between the tip chord of the anterior and posterior wing rationally, if these values are 22 mm and 100 mm, it both can achieve optimization and is convenient for engineering application.

Key words： "diamond back" wing; turbulence model; vertical height difference; aerodynamic characteristics; numerical simulation
