An optimization of the cavity geometry in home ovens optimizes the gasses flow. It improves the heat transfer during cooking process.



A numerical simulation by CFD plus an empirical study of the flow pattern into a home oven, allows to optimize the geometrical form of the oven's cavity. An optimal geometry improves the heat transfer due to natural convection which reduces the cooking time, the gas consumption and the carbon dioxide emissions to the enviroment.

The geometry optimization can be carried out by means a set of deflector plates, which can be added to an existing oven. Due to the geometry of the majority home ovens has standard dimensions, a simple set a deflectors can be economically manufactured.

Preliminar analysis show that savings about 25-30% in gas and emissions can be achieved by the instalation of the set of deflector into a home oven.

In a first stage, the set of deflectors can be installed in existant home ovens. In a second stage, a new geometrical design can be implemented in new home ovens.
