The use of helical inserts for the enhancement heat transfer outside tube bundles.

Amélioration des échangeurs thermiques tubulaires par l'utilisation d'inserts hélicoïdaux à l'extérieur des tubes.

Author(s) : MANSUR S. S.

Type of monograph: Doctoral thesis

Summary

Laws of friction and thermal exchange within this geometry were determined experimentally and programmed. Pressure and flow measurements, as well as visualization of the flow were achieved on a transparent-plexiglas exchanger. Results obtained during this step permitted the flow distribution inside the system to be assessed and to identify the elements necessary to validate the calculations. The aspect of the buoyant diffusion inside the tubular beam was approached by a simple visualization experiment. The presence of inserts facilitates blending and dispersion.
