This monograph is devoted to the study of heat transfer and turbulent mixing in gas-cooled channels, considering the effects of body forces (natural and centrifugal forces). It presents the results of detailed measurements of hydrodynamic and thermal characteristics in a vertical tube with coincident directions of forced and free convection (aiding flows) at various heat loads, and also in curved tubes and coils. Numerical results for the characteristics of turbulent transport in mixed turbulent convection are reported. Experimental apparatus and investigation techniques are described. The results are correlated in the form of similarity relations suitable for practical application over a wide range of operating conditions and geometric parameters.
