Theoretical and experimental studies on heat exchange in the condenser, applicable to a hydrogen isotope separation system.

Author(s) : GHERGHINESCU S., VIJULIE M., SEBASTIAN S.

Summary

The increasing use of numerical methods for thermal exchanger dimensioning led to the development of several computing models able to cope with two-phase flow (with or without phase shift). Regarding pure vapour condensation in a stratified two-phase flow, different relations are used to obtain the average heat transfer coefficients as well as among those measured. Also, there is a noticeable difference between the two sets of coefficients, theoretical and measured. This study plays an important role in the ensuring of a constant liquid level in the column for hydrogen isotope separation. The thermodynamics were modelled based on the Beattie-Bridgman relation. The proposed models address high-performance installations, especially those in the nuclear energy field.
