Abstract :
The spatial flow around an asymmetric wing segment J-78 with a twist is studied. Solutions of Reynolds-averaged Navier-Stokes equations are obtained with Ansys CFX - 13 finite volume solver. A three-dimensional mesh with elongated along the wing span elements near the wing is used. The pressure distribution on the wing surface is studied in the certain range of average angle of attack. This range corresponds to coalescence and splitting of the super-sonic regions above the upper surface of the wing.
