Etude sur l'écoulement transitoire diphasique pendant la mise en route des systèmes frigorifiques et de conditionnement d'air.

Investigation of transient two-phase flow during refrigeration and air-conditioning system startup.

Auteurs : HEDRICK M. J., JASSIM E. W., NEWELL T. A.

Résumé

The characteristics of transient two-phase refrigerant flow, specifically slug flow, related to air-conditioning and refrigeration system startup conditions are investigated. The apparatus used to collect information necessary for modelling slug motion is described. Flow visualization techniques and implementation of optical film thickness sensors are described. Important physical trends of the flow for an air/water system are discussed using flow visualization images and experimental data. Analytical models describing slug motion for an air/water system are developed. These models are applied to the experimental data. Their effectiveness in predicting the transient slug motion are analyzed and compared.
