The priority programme "Liquid Atomisation and Spray Processes" involves experimental studies and numerical simulations of fundamental atomisation mechanisms and transport processes in sprays. Various types of atomisation are being studied: liquid sheet, periodically excited jets, pressure swirl, hollow cone, effervescent and nozzles with cavitation. The experimental studies are supported by a high-speed visualisation system (100MHz, 8 frames), shared by all project partners. Other measurement techniques include synchronised photography, the phase Doppler technique, laser-induced fluorescence, particle image velocimetry and gas-phase image velocimetry. Several studies examine atomisation into elevated or oscillating pressures. Many of the experimental studies have accompanying project partners working on the simulation of the atomisation process. These simulations are performed largely using direct numerical simulations, employing combinations of interface capturing and interface tracking routines. Close co-operation is maintained to insure well-defined boundary and initial conditions.

优先项目“液体雾化和喷雾过程”涉及基本雾化机制和喷雾运输过程的实验研究和数值模拟。人们正在研究各种类型的雾化：液体片状、周期性激发射流、压力旋流、空心锥、泡腾式和空化喷嘴。实验研究由高速可视化系统（100MHz， 8帧）支持，由所有项目合作伙伴共享。其他测量技术包括同步摄影、相位多普勒技术、激光诱导荧光、粒子图像测速和气相图像测速。有几项研究考察了雾化过程的升高或振荡压力。许多实验研究都有项目合作伙伴参与模拟雾化过程。这些模拟主要使用直接数值模拟，采用界面捕获和界面跟踪例程的组合。保持密切合作，以确保明确的边界和初始条件。
