The transition-to-turbulent-flow regime experimental data are analyzed to show the generalized dependencies of convection on variables that describe the flow geometry and thermal-hydraulic conditions. Based on this parametric analysis, predictive equations are developed for calculation of heat transfer at the initial section of the tube with twisted-tape insert with both axial and radial fluid inlet. %8 2015-09-30
