Abstract

In the article, mathematical modeling of turbulent flows and heat transfer in pipes with turbulators of a semicircular cross section was carried out to determine of these ranges numbers Reynolds (Re = 8000 ÷ 38000), investigated in the experiment [16] of the flows of nitric acid HNO3 (Pr = 3.23). For an adequate comparison of the obtained calculationstn data from experienced [16] solved the problem of the effect of increasing the surface when using artificial turbulators of a semicircular cross-section flow in pipes on the effect of increasing heat transfer. As a result, of these settlement tov It was identified xgood agreement of theoretical data with the corresponding experimental data [16]; the influence of the geometrical parameters of the channel and the regimes of the coolant flow on the intensified heat transfer under the given conditions was revealed. Verification of settlements tn data experiment allowed spend similar calculations you for an extended range of Reynolds numbers, an order of magnitude higher than the experimental range (Re = 80000 ÷ 380000).
