  • the present invention relates to the field of fluid containers. More specifically, the present invention relates to the field of fluid containers containing a baffle for controlling heat absorption.
  • Natural gas-fired water heaters are simple units that store part of the energy released by burning of the fuel inside an insulated tank that is filled with water.
  • a superior water heater is able to absorb a greater percentage of the thermal energy liberated by the burning of natural gas, and at the same time, exhibit low heat losses to the environment. Lowering heat losses through insulating the storage tank is widely practiced and promoted. Attempts to increase the heat absorption by the storage tank have been pursued through introducing helical swirl tapes to promote convective and radiative modes of heat exchange. Ways of improving heat absorption and preventing heat loss are continuously sought after objectives.
  • a fluid storage container with a baffle controls the heat absorption percentage of the container. Fluid that is heated adjacent to the surface of a container rises replacing colder fluid which sinks downward, regardless of the baffle. This behavior is able to lead to onset of oscillations in the temperature and flow fields. Due to blockage effect of a thin baffle, multi- cell recirculating vortex structures are observed.

For certain placements and lengths of the baffle, the time rate of the rise of the bulk temperature is increased or decreased.

Abstract

La présente invention concerne un contenant de stockage de fluide doté d'une chicane qui commande le pourcentage d'absorption du contenant. Le fluide qui est chauffé de manière adjacente à la surface d'un contenant fait monter le fluide de remplacement plus froid qui chute, indépendamment de la chicane. Ce comportement est capable de provoquer l'établissement d'oscillations de la température et des champs d'écoulement. L'effet d'obstruction d'une chicane mince fait observer des structures de tourbillon de recirculation à cellules multiples. Le nombre et la puissance de ces tourbillons dépendent de la position et de la longueur de la chicane. Pour certains placements et certaines longueurs de la chicane, le taux d'élévation de la température totale est augmenté ou diminué.
