National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Convective Stability of Incompressible Fluids.

PB255645

Publication Date	1976
Page Count	338
Abstract	When a fluid in the field of gravity is heated nonuniformly, a mechanical equilibrium may form under certain conditions. If the temperature is markedly nonuniform, the equilibrium becomes unstable and the resulting disturbances produce convective motion. On the other hand, if conditions are such as to make equilibrium impossible, convection will set in, however small the temperature nonuniformity. In this case too, the increase of temperature difference leads to a crisis due to the instability of the convective motion itself. Both of the above situations represent special cases of one of the most interesting phenomena in modern hydrodynamics: hydrodynamic instability.
