实验和数值模拟研究了毫米级牛顿液体液滴在压力脉冲作用下的形成和演化过程。在一个模型，大规模的打印头的速度响应记录激光多普勒风速仪，并在拉格朗日有限元模拟作为输入的波形。液滴的形状和位置进行了观察，并与它们的数值模拟得到的类似物。
The creation and evolution of millimeter-sized droplets of a Newtonian liquid generated on demand by the action of pressure pulses were studied experimentally and simulated numerically. The velocity response within a model, large-scale printhead was recorded by laser Doppler anemometry, and the waveform was used in Lagrangian finite-element simulations as an input. Droplet shapes and positions were observed by shadowgraphy and compared with their numerically obtained analogues.
