The simulation showed a satisfactory accuracy in determining average, rms and integral characteristics of the flow, and revealed drawbacks in the existing model relations describing the local properties of turbulence. The calculation results was compared with the DNS calculations by other authors found in literature, as well as with the RANS-calculations performed in the STAR-CCM+ code. In this paper, the numerical simulation of turbulent heat transfer in a circular pipe was performed in a wide range of Reynolds numbers using nonparametric MILES-method CABARET on grids with an incomplete resolution of the turbulence spectrum, as well as with the use of the STAR-CCM+ code in a LES-approximation.
