Traditional technologies for clay brick burning are often confronted with firing problems. The produced brick is of poor quality due to poor combustion inside the kiln. So that, cooking plays an important role because it determines the quality of the final product. Therefore, this work presents a transient computational fluid dynamic (CFD) study of firing clay bricks in the traditional oven. The heat transfer modeling in the furnace mainly is made from hydrodynamic equations and combustion reactions. Therefore, numerical simulation is done using ANSYS-Fluent software, using the standard k-ε turbulence model and the Eddy Dissipation turbulent combustion model. The results focused on the flow field, evolution of temperature, and O₂ mass fraction to verify the combustion process inside the kiln. The results show that the kiln reaches the maximum temperature is in order of 900 °C and therefore verification process occurs. Moreover, the results revealed that the O2 mass fraction has the highest values at the inlet and it decreases gradually inside the kiln which gives good evidence about combustion process propagation.

传统的粘土砖烧制技术经常面临烧制问题。由于窑内燃烧不良，生产出的砖质量较差。因此，烹饪起着重要作用，因为它决定了最终产品的质量。因此，这项工作提出了在传统烤箱中烧制粘土砖的瞬态计算流体动力学 (CFD) 研究。炉内传热建模主要由流体动力学方程和燃烧反应组成。因此，数值模拟是使用ANSYS-Fluent 软件，使用标准k-ε 湍流模型和Eddy Dissipation 湍流燃烧模型进行的。结果集中在流场、温度演变和 O ₂质量分数来验证窑内的燃烧过程。结果表明，窑炉达到的最高温度约为 900 °C，因此进行了验证过程。此外，结果表明，O2 质量分数在入口处具有最高值，并且在窑内逐渐减小，这为燃烧过程的传播提供了良好的证据。
