Abstract
The present invention relates to a method of confining pollution generated in the top volume and/or in the bottom volume of an enclosure filled with a fluid, i.e. either a gas, which is in general air, or a liquid, which is in general water, the method confining the pollution by thermal stratification. In said method the mean temperature of said top volume is maintained higher than the mean temperature of said bottom volume by an amount that is sufficient to ensure that said two volumes are separated by a turbulent intermediate zone of narrow width, referred to as the “mixing zone”, within which a steep temperature gradient is maintained; said intermediate zone constituting a virtual confinement barrier in a horizontal plane. The present invention also relates to apparatus associated with the method.
