WebApr 12, 2024 · In this paper, a pitching NACA 0012 airfoil is simulated in the slip flow regime by solving the Navier–Stokes equations subjected to the Maxwell slip and Smoluchowski jump boundary conditions. The rhoCentralDyMFoam solver of the OpenFOAM software has been modified to handle these boundary conditions. The effects of several parameters … WebHigh-lift airfoils are complemented by trailing and leading edge flap systems. The required lift coefficient is achieved with the help of these flaps and slots in the wings, without compromising aerodynamic efficiency or performance. The complete set of CFD simulation software from Cadence can help designers with high-lift airfoil design. WebJun 28, 2024 · Abstract. The ground effect aerodynamics and flow physics of a 2D dragonfly wing hovering (the Reynolds number is 157) in an inclined stroke plane are investigated via solving 2D unsteady incompressible laminar flow Navier–Stokes equations.
