基于CFD和RSM的红茶萎凋机性能参数优化
Optimization of Performance Parameters of Black Tea Withering Machine Based on CFD and RSM
摘要
Abstract
In order to ascertain the influence of the structural parameters of the withering machine on withering performance, the numerical simulation analysis of withering environment was carried out by the fluid mechanics software. The temperature-integrated index after the dimensionless was used as the evaluation index of the withering performance and the response surface methodology (RSM) was used to optimize the three factors (the withering layer height x1, the withering machine and the withering room space x2, and the gas position x3) that affect withering quality. The result shows that the order of importance of each factor on the withering quality was as follows: gas path position, withering machine layer height, space distance. The best set for temperature field performance of the black tea withering machine were x1=10 cm, x2=10 cm, x3 =149.6 cm. The model’s R2=0.968 3, adjR2=0.927 5, the standard deviation was 0.061. The theoretical and actual values of the optimal scheme were: 0.951 9 and 0.909 6, respectively. The CFD and RSM fusion analysis method was suitable for optimizing the performance parameters of the black tea withering machine.关键词
