Abstract

Analysis of literature data shows that among constructive heat exchange enhancement methods, application of tubes with transversely annular turbulators is of great interest. Results of investigations of the tubes with transverse collars and flow core energizers showed that with increase in Reynolds numbers, values of relative heat exchange and resistance coefficients rise. For the heat exchange enhancement, transition interval with the highest values of the heat exchange and resistance coefficients is the promising. However, increase in the heat exchange coefficients leads the resistance coefficients. It was defined that maximal values of parameters under the investigation fall at the step of arrangement of annular apertures equal to 10. Equations, taking into account vortex interaction mechanisms beyond the collars and spherical thickenings, as well as relation between stream-lined barrier arrangement steps, are offered to describe results.
