Abstract EN
A two-dimensional (2D) jet flow and temperature field are simulated by using k-ε T.
C.
model and compared with other three nontemperature corrected models, which are standard k-ε, RNG k-ε, and SST k-ω model.
Then based on the calculated results, the spectral infrared radiation characteristics within 4∼5 μm of the 2D jet flow were calculated.
By comparing the computed results of the velocity, temperature field, and infrared radiation with the experimental measurements, it shows that the k-ε T.
C.
model predicts mean flow mixing more rapidly and the turbulent kinetic energy dissipates earlier than with no temperature correction; the k-ε T.
C.
model could give a good prediction for the velocity and temperature distributions on the centerline of the 2D hot gas jet, but not on the locations off the centerline.
The maximum computation error of the 2D hot jet infrared radiation is decreased from 86% to 26%, and the accuracy of the computation is greatly improved.
