In this paper, we will present the validation of numerical methodology for the improvement of baking performance of a forced convection oven. The baking performance will be assessed as the degree of uniformity between browning and temperature distribution in the oven. We found a linear relationship between the experimentally measured grade of browning and the simulated temperature distribution. Six different designs of oven fan cover were compared through numerical simulations, where a time-dependent 3D numerical model with radiative and convective heat transfers mechanism was used. The results were used in a linear model to estimate the grade of browning. The results were validated with the experimental measurements of baked shortbread using an old and improved-upon oven design. The grade of browning was determined experimentally by the colour contrasts method, based on the colour space CIE L*a*b. The results show that the improved fan cover performs better than the existing fan cover.
