高效清洁在各种工业领域都是一个相当大的挑战。实验室规模的清洗测试是一种研究操作参数对清洗结果的影响并评估所需努力的方法。本文研究了冲击射流清洗过程。测试设置和评估方法能够测量作为时间函数的由射流清洁的圆形区域。在最相关的工业操作参数的变化下进行了基于食品的模型土壤的清洁测试：喷嘴直径（0.39至3.30 mm），压力（0.1至5.0 bar）和喷嘴距离（16至184 mm）。前两个参数表现出幂律依赖性，而后者被忽略，由于相干射流结构。提出了一个半经验模型，可用于优化清洗过程。不同的工艺相关边界条件导致不同的最佳解决方案，例如，最大限度地减少清洁时间、流体消耗或总清洁成本。
Efficient cleaning is a considerable challenge in various industrial fields. Laboratory scale cleaning tests are an approach to investigate the influences of operating parameters on the cleaning result and to assess the required efforts. In this paper an impinging jet cleaning process was studied. The test set-up and evaluation method enables the measuring of the circular area cleaned by the jet as a function of time. Cleaning tests with a food based model soil were carried out under variation of the most relevant industrial operating parameters: nozzle diameter (0.39 to 3.30 mm), pressure (0.1 to 5.0 bar) and nozzle distance (16 to 184 mm). The first two parameters showed a power-law dependency, while the latter was neglected due to the coherent jet structure. A semi-empirical model is presented which can be used to optimize the cleaning process. Different process-related boundary conditions lead to different optimal solutions, e.g. to minimize the cleaning time, fluid consumption or the total cleaning costs.
