Taguchi metodu kullanılarak mürekkep püskürtülmesinin optimizasyon analizi

Öz

Mürekkep püskürtmeli yazıcılar, yüksek çözünürlüğü kabul edilebilir bir hızla birleştirmek ve düşük maliyet ile çıktı almak için etkili araçlardır. Bu çalışmada, iki fazlı akışda mürekkep püskürtmeli damlacıkların ağırlık değişimini araştırmak için sıkıştırılamaz NavierStokes denklemleri kullanıldı. Mürekkep rengi için siyah, kırmızı ve mavi, kanal giriş yarıçapı için 0.02, 0.03 ve 0.04 mm ve giriş hızı için 0.2, 0.4 ve 0.6 m/s alınmıştır. Taguchi analizi yapılmış ve mürekkep ağırlığı üzerinde en etkili parametrenin giriş hızı olduğu görülmüştür. Ağırlık maksimizasyonu için optimum koşulların siyah renk, 0.02 mm kanal yarıçapı ve 0.6 m/s giriş hızı olduğu belirlenmiştir. Optimum koşullar belirlendikten sonra farklı renkli mürekkeplerdeki değişimi tespit etmek için Comsol programı ile sayısal olarak damlacık akış analizi incelenmiştir. Daha yüksek yoğunluk ve viskoziteye sahip mürekkepler için damlacık sıvı miktarının daha fazla olduğu ve hedef alana ulaşma süresinin daha kısa olduğu görülmüştür.

Optimization analysis of the inkjet using the Taguchi method

Öz

Inkjet printers are effective tools for combining high resolution with acceptable velocity and low cost output. In this study, the incompressible Navier-Stokes equations were used to investigate the weight change of the inkjet droplets for the two-phase flow. For the ink color black, red and blue, for the nozzle inlet radius 0.02, 0.03 and 0.04mm, and for the inlet velocity 0.2, 0.4 and 0.6 m/s were taken. Taguchi analysis was performed, and it was seen that the most effective parameter on ink weight was the inlet velocity. It has been determined that the optimum conditions for weight maximization are black color, 0.02mm nozzle radius and 0.6 m/s inlet velocity. After determining the optimum conditions, droplet flow analysis was numerically carried out with the Comsol program to detect the change in different colored inks. It showed that the droplet fluid amount was greater and the time it took to reach the target area was shorter for inks with higher density and viscosity.
