摘要: ABSTRACT A circular jet in a crossflow is simulated numerically using commercial CFD code. grid resolution study performed to find that yields grid-independent solution. The three high-Reynolds-number k -e models, the two -ω six low-Reynolds-number models as well Reynolds stress model have been used. In all calculations, near-wall regions are resolved way down wall and no functions Jet velocity ratio 3.3. numbers of 317,000 8,130, respectively. Results show should be very fine obtain There considerable differences between turbulence models. standard closest measured values. SST also quite satisfactory. RNG gave nonphysical profiles. Contrary expectations, did not predict profiles well.
