Question
What is the physical significance of the Fourier number? Will the Fourier number for a specified heat transfer problem double when the time is doubled?
Instant Answer
Step 1
It is defined as the ratio of the heat conduction rate to the heat storage rate in a material. Mathematically, it is given by: Fo = αt/L² where α is the thermal diffusivity of the material, t is the time, and L is the characteristic length (such as the thickness Show more…
