Abstract: 
The behavior of multi-jet impinging flows with fountain formation is important for the design of vertical takeoff and landing (VTOL) aircrafts near the ground. In this work, the flow field generated by the impingement of two axisymmetric turbulent jets on a flat plate was studied. The incompressible flowfield characteristics of twinjet impinging and upwash fountain formation with different jet spacing and height above the ground were considered. The SIMPLE algorithm, the k - e and k - w two-equation turbulence models and the QUICK convection discretization scheme were employed. The agreement of our calculations with the experimental data is relatively good.
