摘要 Temporally evolving supersonic turbulent channel flows are simulated using direct numerical simulation (DNS) approach at Mach number 2.56, Reynolds number 7000 with water vapor (H2O) mass fraction from 0.00 to 0.161 to study the air vitiation effects. Then, the turbulent statistical characteristics and velocity-temperature correlations have been studied based on the DNS database. It is found that in fully developed turbulent channel flow, many of turbulent statistical characteristics used to express supersonic turbulent channel flow of pure air also hold for the H2O considered. After a nondimensional static temperature parameters introduced, the mean velocity-temperature correlation collapses between current DNS results. The results of strong Reynolds analogy decrease with H2O mass fraction increasing, and modified strong Reynolds analogy show a better agreement than original strong Reynolds analogy. In addition, the correlation Ru’T’isn’t remained the same between the different H2O mass fraction cases. © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA.
