In summary, the Fourier Number, represented as Fo, is a dimensionless number used in heat transfer calculations to determine the ratio of heat conduction to thermal energy storage. It is calculated by dividing the product of thermal diffusivity and time by the square of the characteristic length. It is primarily used in heat transfer calculations, but can also be applied in other fields such as mass transfer and fluid dynamics. A high Fourier Number indicates that heat conduction dominates, while a low Fourier Number indicates that thermal energy storage is significant. It can be calculated using the formula Fo = αt/L^2, where α is the thermal diffusivity, t is time, and L is the characteristic length.

This is on a building in Korea, and the F0 made me think of the Fourier number, but the rest of the formula is unfamiliar to me. Does anyone recognize it?
It might be the fundamental frequency of the brick wall, a private joke between the architects and engineers, since earthquakes are possible and the "writing is on the wall".
