摘要:
为了构建一个能真实反映织物特征的多孔介质模型首先测试不同厚度的织物在不同压差下的气流速度;然后对测试数据进行拟合分析得到压降与气流速度之间的函数关系,并利用多孔介质数学模型与拟合函数之间的关系,得到多孔介质模型的参数;最后利用多孔介质模型进行流体计算,证明模型可以用于模拟分析。结果表明:在一定范围下,压降和气流速度之间具有二次函数关系;得出函数拟合值与测试值之间的误差小于7%,模拟值与测试值之间的误差小于6%。所以随着织物厚度增加函数关系趋于一致,构建的多孔介质模型符合织物的实际情况,并可以用于研究气流在织物内部的流动特征。
Abstract:
In order to build a porous media model that truly reflects the characteristics of the fabric, firstly, the airflow velocity of fabrics with different thicknesses was tested at different pressure differentials. Then, the test data were fitted to obtain the functional relationship between pressure drop and airflow velocity, and the parameters of the porous media model were gained according to the relationship between the mathematical model of porous media and the fitting function. Finally, the porous media model was used for fluid calculation, demonstrating that the model could be used for simulation analysis. The results showed that, under a certain range, there is a quadratic function relation between the pressure drop and the airflow velocity; the error between the function fitting value and the measured value is less than 7%, and the error between the simulated value and the measured value is less than 6 %. Therefore, as the fabric thickness increases, the functional relationship tends to be consistent. The constructed porous media model conforms to the actual situation of the fabric and can be used to study the flow characteristics of the air flow inside the fabric
