The flowfield of dual, parallel planar turbulent jets is investigated experimentally using an x - type hot - wire probe and numerically by solving the Reynolds - averaged Navier - Stokes equations. The performance of both differential Reynolds stress (RSM) and standard k - E turbulence models is evaluated. Results show that the numerical models predict the merge and combined point characteristics to good accuracy. However, both turbulence models show a narrower width of the jet envelope than measured by experiment. The predicted profiles of the mean velocity along the symmetry plane agree well with the experimental results.
