dc.description.abstractUsing 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.en
