Casserole pan thermal losses - QuickField simulation example
Engineering question
How to calculate the power required to heat a casserole pan to boiling temperature?
Answer
Solve a 3D steady-state heat-transfer model at boiling temperature; the net heat loss from the pan is the required heating power.
Typical applications
heated cookware vessels, electric cooking heaters, thermal vessel walls

Simulation problem
Problem Type3D problem of heat transfer.
Geometry
Given
Thermal conductivity of metal λ = 40 W/K-m.
Convection coefficient α = 15 W/(K·m².
Ambient air temperature T0 = 20 °C.
Casserole inside temperature T = 100 °C.
Task
Casserole pan is heated from the bottom side up to water boiling temperature. Determine the required power.
Solution
Since the geometry model is symmetrical we can reduce the simulation to only one half of the pan.
Results
Temperature distribution in the casserole pan. Net power losses are 1200 W.
