Maximum and minimum energy in vortex motion

الملخص EN

This paper is discussion the Maximum and minimum energy in vortex motion exploited the conservation of vorticity as well as energy in two-dimensional motion of an incompressible inviscid fluid, to find some quite general criteria for stability of steady basic flows, and also steady Bènard convection sets in at the critical value of the Rayleigh number.

This paper also discussion some experiments with a silicone oil (of Prandtl number100).
