应用案例研究:FLOW-3D计算机模拟帮助提高喷墨打印头性能

 

Developing a new inkjet printhead technology is challenging because the extremely high speed and tiny size of these microelectromechanical systems (MEMS) make them very difficult to measure or observe. Océ Technologies has met this challenge by using a combination of several different computer simulation technologies to understand how inkjet design parameters affect printhead performance. For the computational fluid dynamics work, Océ used FLOW-3D from Flow Science in Santa Fe, New Mexico, to predict the free-surface flow with surface tension and wall flexibility. Simulations enable Océ engineers to quickly evaluate the performance of a wide range of possible designs and zero in on the most promising alternatives into which substantial time and expense required for MEMS prototyping is invested. Using CFD simulation to confirm and improve their designs, Océ was recently able to develop new wide-format printers delivering a printing speed much faster than the current generation of printers.
