The drying process is a step of ceramic brick production which requires the control of process variables to provide a final product with a porous uniform structure, reducing superficial and volumetric defects and production costs. Computational fluid dynamics (CFD) is an important tool in this process control, predicting the drying physical phenomenon and providing data that improve the industrial efficiency production. Furthermore, research involving CFD brick drying has neglected the effects of oven parameters, limiting the analysis only to the bricks. In this sense, the aim of this work is to numerically study the hot air-drying process of an industrial hollow ceramic brick in an oven at 70 °C. The results of the water mass and temperature distributions inside the brick, as well as moisture, temperature, velocity and pressure fields of the oven drying air at different process times are shown, analyzed and compared with experimental data, presenting a good agreement.
干燥过程是陶瓷砖生产中的一个步骤，该步骤需要控制工艺变量，以提供具有多孔均匀结构的最终产品，减少表面和体积缺陷以及生产成本。计算流体动力学（CFD）是此过程控制中的一项重要工具，可预测干燥物理现象并提供提高工业生产效率的数据。此外，涉及CFD砖干燥的研究忽略了烘箱参数的影响，仅将分析局限于砖。从这个意义上讲，这项工作的目的是对工业空心陶瓷砖在70°C烘箱中的热风干燥过程进行数值研究。展示了砖内部水质量和温度分布的结果，以及不同工艺时间下烘箱干燥空气的湿度、温度、速度和压力场，进行了分析并与实验数据进行了比较，结果显示出良好的一致性。
