“…Another possible scenario when two drops collide in a vacuum environment is the fragmentation of the drops. Many studies has been proposed for the numerical simulation of the coalescence and break up of droplets (Azizi & Al Taweel, 2010;Cristini et al, 2001;Decent et al, 2006;Eggers et al, 1999;Foote ,1974;Jia et al, 2006;Mashayek et al, 2003;Narsimhan, 2004;Nobari et al, 1996;Pan & Suga, 2005;Roisman, 2004;Roisman et al, 2009;Sun et al, 2009;Xing et al, 2007;Yoon et al, 2007). In these studies, the authors propose different methods to approach the dynamics of liquid drops by a numerical integration of the Navier-Stokes equations.…”

“…This method can describe the ink channel dynamics, although the accuracy of analytical models is lower than numerical models. Based on several assumptions and simplifications, analytical models can provide a simple and timesaving way to model-based control droplet generator with a sufficient accuracy [6].…”

Abstract. The major challenge in 3D electronic printing is the print resolution and accuracy. In this paper, a typical mode -lumped element modeling method (LEM) -is adopted to simulate the droplet jetting characteristic. This modeling method can quickly get the droplet velocity and volume with a high accuracy.Experimental results show that LEM has a simpler structure with the sufficient simulation and prediction accuracy.

“…However, numerical models are rather complex and therefore computationally expensive. In the last decade, analytical modeling approach is gradually employed to describe the ink channel dynamics, although their accuracy is lower than numerical models [4]. Based on several assumptions and simplifications, analytical models provide a simple and timesaving way to model-based control droplet generator with a sufficient accuracy.…”

Abstract. The major challenge in printable electronics fabrication is to effectively and accurately control a drop-on-demand (DoD) inkjet printhead for high printing quality. In this paper, a prediction model based on Lumped Element Modeling (LEM) is proposed to search the parameters of driving waveform for obtaining the desired droplet properties. Although the evolution algorithms are helpful to solve this problem, the classical evolution algorithms may get trapped into local optimal due to the inefficiency of local search. To overcome it, we present an improved artificial bee colony algorithm based on K-means clustering (KCABC), which enhances the population diversity by dynamically clustering and increases the convergence rates by the modification of information communication in the employed bees' phase. Combined with KCABC, the prediction model is applied to optimize the droplet volume and velocity of nanosilver ink for high printing quality. Experimental results demonstrate the proposed prediction model with KCABC plays a good performance in terms of efficiency and accuracy of searching the appropriate combination of waveform parameters for printable electronics fabrication.
