Turbulent Flow Laminarization Under Conditions Of Spatial and Heat Deformations in Pipelines

摘要

Investigation represented below is devoted to flows in channels with complicated wall configuration, containing cross- section variation along pipes (so-called convergent and divergent pipes) as well as under conditions of intensive heat supply to wall. Investigation was carried out in terms of original two-parametric k-L turbulence model adapted for internal flows on the basis of experimental data [1]. Obtained results are compared with experimental ones. Effects of laminarization are fixed, practical recommendations on use of these effects are given.
