Electric Oven Application
The oven model was developed to show how RadTherm/ WinTherm can be used to design appliances. It should be noted that temperatures and dimensions were only approximated for demonstration purposes. TAI software has an exceptionally fast radiation solver which allows complex models such as this to be solved quickly.
The element inside the oven operates on a thermostatic cycle.  In this case assigned temperature was used.  However, assigned wattage could also have been used to allow element temperature to vary.  Curves have been applied to simulate this cycling.   Also the convection applied to surfaces inside the oven is based on a fluid temperature that follows the thermostatic oven cycles.  The burner under the pan is set to turn on at a high temperature to heat the pan more quickly and then temperature is reduced and held constant.
