Hydrodynamics and heat transfer in complex pipelines at any configuration of wall

The paper is devoted to analysis of flows with variable configuration of wall (in confusers and diffusers) and wall strong heating. Numerical simulation in terms of original two-parametric k-L turbulence model on the basis of experimental data is performed. Obtained results are compared with experimental ones. Effects of laminarization are fixed, practical recommendations on use of these effects are given.
