The Computational Fluid Dynamics (CFD) analysis of flow and temperature distribution in heating ovens used in bakery shops, to keep the foodstuffs warm, is attempted using the finite element technique. The oven is modeled as a two-dimensional steady state natural convection heat transfer problem. The effects of a number of heaters and total input power on temperature uniformity of foodstuffs are studied. The heaters are located at the bottom with different number of coils (one, two and three) and different input power (500 W, 600 W, 800 W and 1000 W) are analyzed. Placing two coils with input power 800 W at the bottom of the oven improves the uniform heating of foodstuffs than the ovens with one and three coils. The analysis shows that if heaters are located at the bottom along with additional flow guidance arrangements, energy-efficient oven configuration can be obtained.

Technological advancements and improved standards of living have increased the per capita energy use and the associated pollution to an alarming level. A survey carried out at 13 most industrialized nations has shown that about 38% of the total energy is spent for comfort applications [1]. Chen [2] strongly points out that similar aspects will be repeated in the developing nations and meeting such exponentially growing energy demand in the developing nations will be a major task among others in this 21st century. In India, the domestic sector energy consumption is 15% of the total energy consumption during 1993. During the five-year period (1993-98), the average electricity consumption has grown by 48%, while the domestic sector section consumption raised by 92%, mainly because of comfort applications. Thus, energy needs to be conserved wherever possible.
