Abstract:
Gravitational filtration convection of an incompressible fluid in ring sectors is studied. The bifurcation and development of families of convective regimes are studied using equations in polar coordinates and a finite-difference scheme that preserves the cosymmetry of the original problem. The occurrence of instability for trapezoidal and semiring areas is analyzed for stationary states.
Keywords:
filtration convection, finite-difference scheme, family of stationary regimes, cosymmetry.
