摘要：

The effectiveness of the heat exchange intensifier "rib-twisted wire" is considered in this paper. The main goal was to study the influence of the wire coiling step t on heat transfer and hydraulic resistance for different values <(H)over dot> of the dimensionless height of the edge <(H)over dot>, as well as some results on heat exchange during bubbly boiling in an annular channel. Given: a brief description and an image of the heat exchange intensifier "rib-twisted wire"; generalized results of studies of heat exchange and hydraulic resistance in the annular channel in the single-phase convection with different geometric characteristics of the intensifier; empirical correlations of the generalized experimental results that allow to calculate the coefficient of hydraulic resistance and heat transfer in the range of regime parameters in the single-phase convection that is being studied. some results of experiments in bubbly boiling regimes and near-critical thermal loads.
