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). When the Rayleigh number is below the critical value for that fluid, heat transfer is primarily in the form of [[heat conduction|conduction]]; when it exceeds the critical value, heat transfer is primarily in the form of [[convection]].
 
The Rayleigh number is named after [[John Strutt, 3rd Baron Rayleigh|Lord Rayleigh]] and is defined as the product of the [[Grashof number]], which describes the relationship between [[buoyancy]] and [[viscosity]] within a fluid, and the [[Prandtl number]], which describes the relationship between momentum diffusivity and thermal diffusivity. Hence the Rayleigh number itself may also be viewed as the ratio of buoyancy and viscosity forces times the ratio of momentum and thermal diffusivities.
 
==Definition==
For [[free convection]] near a vertical wall, the Rayleigh number is defined as
 
:<math>\mathrm{Ra}_{x} = \frac{g \beta} {\nu \alpha} (T_s - T_\infin) x^3 = \mathrm{Gr}_{x}\mathrm{Pr} </math>
 
where
* ''x'' = Characteristic length (in this case, the distance from the leading edge)
* Ra<sub>''x''</sub> = Rayleigh number at position ''x''
* Gr<sub>''x''</sub> = [[Grashof number]] at position ''x''
* Pr = [[Prandtl number]]
* ''g'' = acceleration due to gravity
* ''T<sub>s</sub>'' = Surface temperature (temperature of the wall)
* ''T<sub>∞</sub>'' = Quiescent temperature (fluid temperature far from the surface of the object)
* ''ν'' = [[Kinematic viscosity]]
* ''α'' = [[Thermal diffusivity]]
* ''β'' = [[Coefficient of thermal expansion|Thermal expansion coefficient]] (equals to 1/''T'', for ideal gases, where ''T'' is absolute temperature)
 
In the above, the fluid properties Pr, ''ν'', ''α'' and ''β'' are evaluated at the [[film temperature]], which is defined as
 
<math>T_f = \frac{T_s + T_\infin}{2}</math>
 
For most engineering purposes, the Rayleigh number is large, somewhere around 10<sup>6</sup> to 10<sup>8</sup>.
 
 
For a uniform wall heating flux, the modified Rayleigh number is defined as <ref>M. Favre-Marinet and S. Tardu, Convective Heat Transfer, ISTE, Ltd, London, 2009 </ref>
 
<math>\mathrm{Ra}^{*}_{x} = \frac{g \beta q''_o} {\nu \alpha k} x^4 </math>
 
where
* ''q"<sub>o</sub>'' = the uniform surface heat flux (W/m<sup>2</sup>)
* ''k'' = the thermal conductivity (W/m•K)
 
 
===Geophysical applications===
In [[geophysics]], the Rayleigh number is of fundamental importance: it indicates the presence and strength of convection within a fluid body such as the Earth's [[earth's mantle|mantle]]. The mantle is a solid that behaves as a fluid over geological time scales. The Rayleigh number for the Earth's mantle, due to internal heating alone, Ra''<sub>H</sub>'' is given by
 
<math>\mathrm{Ra}_H = \frac{g\rho^{2}_{0}\beta HD^5}{\eta \alpha k}</math>
 
where ''H'' is the rate of [[radiogenic heat]] production, ''η'' is the dynamic viscosity, ''k'' is the [[thermal conductivity]], and ''D'' is the depth of the [[Mantle (geology)|mantle]].<ref name=Bunge>{{cite journal |first=Hans-Peter |last=Bunge |last2=Richards |first2=Mark A. |last3=Baumgardner |first3=John R. |year=1997 |title=A sensitivity study of three-dimensional spherical mantle convection at 10<sup>8</sup> Rayleigh number: Effects of depth-dependent viscosity, heating mode, and endothermic phase change| journal = [[Journal of Geophysical Research]] | pages = 11991–12007 | volume = 102 |issue=B6 |doi=10.1029/96JB03806 |bibcode = 1997JGR...10211991B }}</ref>
 
A Rayleigh number for bottom heating of the mantle from the core, Ra''<sub>T</sub>'' can also be defined:
 
<math>\mathrm{Ra}_T = \frac{\rho_{0}g\beta\Delta T_{sa}D^3 c}{\eta k}</math> <ref name=Bunge />
Where Δ''T''<sub>sa</sub> is the superadiabatic temperature difference between the reference mantle temperature and the [[Core–mantle boundary]] and ''c'' is the [[specific heat capacity]], which is a function of both pressure and temperature.  
 
High values for the Earth's mantle indicates that convection within the Earth is vigorous and time-varying, and that convection is responsible for almost all the heat transported from the deep interior to the surface.
