Using a multi-hot (cold) wire probe consisting of four “Xwires”
and two pairs of parallel cold wires, the full turbulent
energy and temperature dissipation rates, denoted as f and f ,
were measured simultaneously in the far region of a slightly
heated circular cylinder wake. The performance of the probe in
measuring the three components of the velocity and vorticity
vectors was examined first. The mean values of the turbulent
energy and temperature dissipation rates were evaluated based
on both the full expressions and the isotropic relations. The
differences between the present measurements of the mean
turbulent energy and temperature dissipation rates and those
reported previously are then analysed.
