A THERMODYNAMIC MODEL TO STUDY THE ENERGY CONSUMPTION OF GAS COOKING OVENS

Simulation is one of the most suitable and easiest method to investigate the efficiency of cooking ovens and to study the different modifications leading to efficiency enhancement. However, this home appliance being simple in design has a complex physics such as the low rate of fuel burning and complicated domain and boundary conditions. Therefore, the 3-D unsteady governing equations are very difficult to solve and even the solution cannot be validated by experimental data properly. In this paper , by simplifying the governing equations, a thermodynamic model is developed to predict the oven behavior, its container, and insulation, including the combustion chamber and control valve operation. The equations are solved by employing a numerical integration algorithm. In addition, an experimental set up is installed and the model is validated by experimental results.
