EXPERIMENTAL DATA ON FAR-WAKE Data are contained in two files: Dynamic-field-data.dat contains profiles of mean velocity, Reynolds stresses, k, epsilon and k turbulent diffusion. Thermal-field-data.dat contains profiles of mean temperature, turbulent heat flux, temperature variance, epsilon_theta and temperature variance diffusion. REFERENCES : 1.

NOMENCLATURE : d = diameter of circular cylinder f = (Ue - U)/Uo Ue = free stream velocity U = local velocity Uo = max. velocity defect L = half-width (based on velocity defect) Te = free stream temperature T = local temperature To = max. excess temperature,(Te-T) along centre line Ts = (T - Te)/To k = turbulent kinetic energy uu, vv, ww = normal Reynolds stress components Eps = rate of dissipation of k Eps_h = rate of dissipation of k in homogeneous flow tt = variance of temperature fluctuation vt = cross-stream turbulent heat flux Eps_t = rate of dissipation of THETAs NU = kinematic viscosity CHARACTERISTICS OF WAKE : (i) Wake producing body : circular cylinder of diameter 2.67 mm. (ii) Measuring station : x/d = 420 At x/d = 420, the values are L = 12.3 mm. Ue = 6.7 m/s. Ue*d/NU = 1190 To = 0.82 deg. Celsius REMARKS : (1) The values of Eps_t are obtained by balancing the equation for THETAs. These values are slightly different from the experimental values of EPSILONtheta. (See Ref.2 above). (2) The final three values in Thermal-field-data.dat for vt and D(theta2v)/2D(eta) (all zero) should be disregarded, since velocities were not measured at these locations.
