Abstract
A liquid jet is used in ink-jet printers, needle-free injections and other important devices. However, it is difficult to generate high-viscous jets using present methods. We propose a generation system for high-viscous liquid jets. We verify the performance of this system and find that this system can generate a high-viscous (1,000 mm^2/s) jets. We present a physical model based on pressure impulse, which can describe all experimental results. In this paper, we reproduce a liquid jet using numerical calculation. The calculated jet velocity agrees with experimental results and the proposed model. The pressure field in a liquid using numerical calculation also agrees with the physical model.
