| 20100180836 | FLUID STORAGE CONTAINERS WITH BAFFLES - 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. The number and strength of these vortices depend on the position and length of the baffle. For certain placements and lengths of the baffle, the time rate of the rise of the bulk temperature is increased or decreased. | 07-22-2010 |
