Layer number dependence of temperature distribution in multi-metal cookware

Multi-layer plate improves thermal, chemical and mechanical properties. Multilayered structure which is exposed to non-uniform heater provides uniform temperature distribution on other side. Numerical modeling using the finite element method has been performed to study the dependence of thermal behavior of multi-metal cookware, which is exposed to irregular heating, on number and thicknesses of layers, materials and diameter of plates. We have studied the behavior of the two important parameters in cooking including mean temperature degree and uniformity on cooking surface through variations of geometric and thermal properties. We have applied Cu, Al, SSt, CrNi, and Ti through one to four layers. The results address that bi-layer plate has the better thermal performance than one, three and four layers as cookware function.
