Convective drying is one of the most energy intensive thermal processes. In convective textile drying, >50%) of the input energy is typically lost to the surroundings. A transient, two-dimensional mathematical model of textile drying in a gas-fired tumble dryer was developed. Mass, momentum, and energy conservation were used to understand the heat and mass transfer phenomena occurring in and around the textiles within the dryer. A moving evaporation front is used to numerically simulate the drying process in the textile. The mathematical model was validated using experiments conducted on a commercial gas-fired tumble dryer. The performance of the distributed parameter and the lumped drying models showed similar agreement when predicting specific moisture ratio and drying efficiency. The 2-D model showed good agreement when predicting the exit temperature of the combustor and drum with average absolute deviations of 4.2% and 7.7%, respectively.

对流干燥是最耗能的热过程之一。在对流纺织品干燥中，>50%) 的输入能量通常会损失到周围环境中。开发了一种在燃气滚筒式干衣机中干燥纺织品的瞬态二维数学模型。质量、动量和能量守恒被用来了解烘干机内纺织品内部和周围发生的传热和传质现象。移动蒸发前沿用于数值模拟纺织品的干燥过程。使用在商用燃气滚筒式干衣机上进行的实验验证了数学模型。在预测特定水分比和干燥效率时，分布参数和集中干燥模型的性能表现出相似的一致性。
