The critical Rayleigh number can be obtained analytically for a number of different boundary conditions by doing a perturbation analysis on the linearized equations in the stable state.
12.
The Rayleigh number can be also used as a criterion to predict convectional instabilities, such as A-segregates, in the mushy zone of a solidifying alloy.
13.
These parameters, together with the Pr and Ck chosen, ensure that the Rayleigh number is large and negative, and thus that the system is stable to convective motions.
14.
This critical value is independent of the composition of the alloy, and this is the main advantage of the Rayleigh number criterion over other criteria for prediction of convectional instabilities, such as Suzuki criterion.
15.
As the Rayleigh number is increased even further above the value where convection cells first appear, the system may undergo other bifurcations, and other more complex patterns, such as spirals, may begin to appear.
16.
Computed results in form of tables, graphs and figures for a fluid with Prandtl number = 0.71 with Rayleigh number ( Ra ) ranging from 10 3 to 10 7 are available in the literature.
17.
When the Rayleigh number is below a critical value for that fluid, heat transfer is primarily in the form of conduction; when it exceeds the critical value, heat transfer is primarily in the form of convection.
18.
In fluid mechanics, the "'Rayleigh number "'( "'Ra "') for a fluid is a dimensionless number associated with buoyancy-driven flow, also known as free convection or natural convection.
19.
In the case of a rigid boundary at the bottom and a free boundary at the top ( as in the case of a kettle without a lid ), the critical Rayleigh number comes out as Ra = 1, 100.65.
20.
Longer spines also make the organisms more buoyant, by decreasing their Rayleigh number ( i . e . increasing the relative importance of water's viscosity ) it is therefore possible that at least the long-spined chitinozoans were planktonic " floaters ".
