In physics and engineering, the Fourier number (Fo) or Fourier modulus, named after Joseph Fourier, is a dimensionless number that characterizes heat conduction. Together with the Biot number, it characterizes transient conduction problems. Conceptually, it is the ratio of diffusive/conductive transport rate by the quantity storage rate and arises from non-dimensionalization of the heat equation.

  • In physics and engineering, the Fourier number (Fo) or Fourier modulus, named after Joseph Fourier, is a dimensionless number that characterizes heat conduction. Together with the Biot number, it characterizes transient conduction problems. Conceptually, it is the ratio of diffusive/conductive transport rate by the quantity storage rate and arises from non-dimensionalization of the heat equation. The transported quantity is usually either heat or matter (particles).The general Fourier number is defined as: The thermal Fourier number is defined by the conduction rate to the rate of thermal energy storage.where: α is the thermal diffusivity [m2/s] t is the characteristic time [s] L is the length through which conduction occurs [m]For transient mass transfer by diffusion, there is an analogous mass Fourier Number (also denoted Fo) defined as:where: "D" is the Diffusivity (m2/s) "t" is the characteristic timescale (s) "L" is the length scale of interest (m)
