The dimensionless time defines the Fourier number, Foh = αt/L2. ... For unsteady state conduction problems in solids, the Fourier number is frequently used as a nondimensional time parameter. Together with the Biot number, the Fourier number can be used to determine the heating or cooling of an object.
