染色机喷嘴缝隙的流动分析与结构优化
|
Abstract:
为了提高染色机环形喷嘴的冲击和牵引性能，通过数值模拟分析研究了四种环形缝隙形状(矩形、锥形、锥直形、维多辛斯基形)喷嘴性能的差异，并对锥直形喷嘴结构参数进行了正交实验，还建立了回归预测模型，并利用算法进行了多目标优化，得到了最优结构组合，最后开展了数值模拟验证。结果表明：在不同性能指标下，锥形、锥直形和维多辛斯基形喷嘴均大于矩形喷嘴，且锥直形和维多辛斯基形喷嘴两者性能接近；优化后的锥直形喷嘴在缝隙入口大小为6.00 mm、直段长度为2.00 mm，出口间隙为1.50 mm以及射流角度为40？时，性能有了进一步的提升。
In order to improve the impact and traction performance of dyeing machine annular nozzles, the differences in the performance of nozzles with four annular gap shapes (Rectangular, Conical, Cone Straight, and Vidocinsky) were investigated through numerical simulation analysis, then orthogonal experimental analysis was carried out on the structural parameters of cone-straight nozzles, and a regression prediction model was also established, and a multi-objective optimization was carried out by using an algorithm to get the optimal structural combinations. And build related experi-ments to verify the simulation model. The results show that: under different performance indexes, the conical, conical straight and Vidocinsky nozzles are larger than rectangular nozzles, and the performance of conical straight and Vidocinsky nozzles are close to each other; the optimized cone straight nozzles with a gap inlet size of 6.00 mm, a straight section length of 2.00 mm, a gap outlet size of 1.50 mm and a jet angle of 40？ provide a further performance improvement.
