摘要

It is shown that a reacting fluid under the action of external forces can develop nonequilibrium stationary structures. The main difference between these nonequilibrium states and the hydrostatic one is the appearance of a velocity field that drives the fluid from the zones where particles are created by reactions to the regions where they annihilate. Although this mechanism is derived here for a perfect fluid subject to gravity, within a particular reaction model and a partial-linearization scheme, the results are reasonably expected to hold in more general situations.
