For free convection near a vertical wall, the Rayleigh number is defined as
where
- x = Characteristic length (in this case, the distance from the leading edge)
- Rax = Rayleigh number at position x
- Grx = Grashof number at position x
- Pr = Prandtl number
- g = acceleration due to gravity
- Ts = Surface temperature (temperature of the wall)
- T∞ = Quiescent temperature (fluid temperature far from the surface of the object)
- ν = Kinematic viscosity
- α = Thermal diffusivity
- β = Thermal expansion coefficient
In the above, the fluid properties Pr, ν, α and β are evaluated at the film temperature, which is defined as
For most engineering purposes, the Rayleigh number is large, somewhere around 106 to 108.

What is the difference between finite element method and Ritz method?
The main difference between the Rayleigh-Ritz method (RRM) and the finite element method lies in the definition of the basis functions. For FEM, these are element-related functions, whereas for RRM these are valid for the whole domain and have to fit the boundary conditions. The Rayleigh-Ritz method for homogeneous boundary conditions leads to the same discretized equations as the Galerkin method of weighted residuals.
Who invented dimensional analysis?
Dimensional analysis was developed in the early 19th century, with significant contributions from several scientists. Notably, the concept was advanced by the French engineer and physicist Henri Poincaré and the British mathematician Lord Rayleigh. However, the foundational principles of dimensional analysis can be traced back even earlier to the work of Galileo and Newton. Overall, it is a collective advancement rather than the invention of a single individual.
What does a negative number multiplied by a negative number equal to?

Dark king rayleigh or jinbei will join luffys crew?
None of them has still joined Luffy's crew. But Silvers Rayleigh is not gonna join the crew. Whether Jinbei joins or not will be decided in Chapter number 649.

What does the Rayleigh Scattering principle refer to in science?
The Rayleigh scattering principle is ascribed to the optical phenomenon that is associated by particles that are smaller than the wavelength of light. It was named after the British physicist Lord Rayleigh.
What is nearer to Rayleigh Leeds or Manchester?
Manchester is further south than Leeds - so Manchester is closer to Rayleigh.
