Abstract

This paper investigates the turbulence properties of passive scalar in turbulent channel flows subject to spanwise rotation by direct numerical simulation. It has been found that the analogy exists between velocity and temperature fluctuations at pressures side in near wall region of the rotating channel flow but the analogy is violated near the suction wall. The influence of the large scale flow structure in rotating channel, known as the Taylor-Görtler vortex, on the turbulence characteristics of temperature fluctuations are revealed and it is the main cause that the different behavior appears near the suction wall.
