Evolution de la distribution de la température dans un réservoir d'accumulation thermique muni de diffuseurs radiaux.

Evolution of temperature distributions in a full-scale stratified chilled-water storage tank with radial diffusers.

Auteurs : MUSSER A., BAHNFLETH W. P.

Résumé

Tests were performed using a 1.4 million gallon (5,300 m3), 13.56 m water depth cylindrical tank with radial diffusers. Nine charge and discharge cycle tests were performed for various flow rates, covering and extending beyond the normal operating range of the system. A method for obtaining thermocline thickness from field data was derived, and a relationship between inlet flow rate and initial thermocline thickness was established. Temperature profiles obtained for charge and discharge cycles at similar flow rates are studied.
