Simple interpolation formula for the estimation of cooling or cooking time.

Author(s) : BART G. C. J.

Summary

One of the dominant practical properties of conductive heat transfer phenomena is a characteristic processing time. This time depends on many quantities: size, geometry, boundary conditions and physical properties as thermal conductivity, heat capacity, density and latent heat effects. It is shown that the geometry or shape of the object is of minor importance if the ratio of volume and surface is taken as size parameter. The solution for an arbitrary heat transfer coefficient is obtained by interpolation between the solution for constant temperature boundary condition and the solution for an infinitely small heat transfer coefficient (uniform temperature in object).
