Abstract
Numerical simulations of two-dimensional (2D) flow obtained by solving the Reynolds-averaged Navier—Stokes (RANS) equations served for the design of 2D thrust vectoring nozzles. Thrust is directed by means of deflectors with different heights placed at the end of the bottom wall. The nozzle was manufactured and tested. A series of experiments were performed in a trisonic wind tunnel. The experimental results obtained by optical methods and pressure measurements are compared with the results of a numerical flow simulation. Differences were observed in pressure distribution along the bottom wall. More detailed research revealed that the real flow considerably deviated from the 2D flow. The primary goal of this work is to provide applicability of the used numerical methods in nozzle design. The results show that RANS 2D simulations with turbulent models based on the Boussinesq approximation are not able to predict reliable enough results for 2D thrust vectoring nozzles.
