Surface engineering processes are used to produce functional coatings. They require surface preparation steps to remove surface contaminants and impart physical anchoring points promoting coating mechanical adhesion to a substrate. VLN Advanced Technologies manufactures customized water jet devices for industry specific applications. To broaden its current market, VLN has recently explored the possibility of modifying its patented pulse water jet (PWJ) technology to enable its use as a green surface preparation method. While these studies have clearly demonstrated the potential of the technology, it has been deemed important by VLN to develop a robust fundamental knowledge of the process physics to allow designing and optimizing a commercially suitable PWJ system for surface preparation. This proposal aims to elucidate the process physics through modeling and experimental validation of the various process parts.

表面工程过程用于生产功能涂层。他们需要表面制备步骤，以去除表面污染物并赋予物理锚定点，从而促进涂层机械粘附到基板。 VLN Advanced Technologies为行业特定应用制造了定制的水喷气设备。为了扩大目前的市场，VLN最近探索了修改其专利脉搏水喷射（PWJ）技术以使其用作绿色表面制备方法的可能性。尽管这些研究清楚地证明了这项技术的潜力，但VLN认为重要的是对过程物理学开发强大的基本知识，以允许设计和优化商业上合适的PWJ系统进行表面准备。该建议旨在通过对各个过程部分的建模和实验验证来阐明过程物理。
