摘要

水刀技术因其优势在当今世界得到了广泛应用,它可以应用于许多工业领域,甚至是医疗和食品行业。喷嘴是水刀中的一个部件,在广泛的工程应用中被用来控制水的流速、速度和喷射压力。本文讨论对纯水射流喷嘴进行 CFD 分析,以获得从三个不同直径的喷嘴喷射出的水的输出量,并选择用于水果去皮和切割过程的有效喷嘴直径。分析使用的压力分别为 200MPa、300MPa 和 400MPa,并对 0.76mm、1.02mm 和 1.27mm 三种不同直径的喷嘴进行了分析。CFD 分析表明,随着水射流压力损失的增加,水射流的出口速度也随之增加。此外,在水果去皮和切割过程中,喷嘴的冲击角度应优先考虑,因为在切割水果之前,水果去皮应平滑均匀。因此,最合适的参数分别是 400MPa 的压力和 1.02mm 的喷嘴直径。这样就能实现预期的水果切割过程,其间距可从 1 毫米到 9 毫米不等。

CFD Analysis of Pure Waterjet Nozzle for Fruit Peeling and Cutting Process
Waterjet Technology has been used vastly in our world nowadays due to its advantages and it can be implemented in many industrial sectors or even in the medical sector and food industry sector. Nozzle is a component that has been utilized in waterjet which is employed in a wide range of engineering applications to control the rate of flow, velocity, and the jet pressure of the water. This paper discusses the CFD analysis on a pure waterjet nozzle to obtain the output of the water that jets out from three different diameters of nozzle and select the effective nozzle diameter to be used for the fruit peeling and cutting process. The pressure used for the analysis are 200MPa, 300MPa and 400MPa, which was analysed for three different nozzle diameter 0.76mm, 1.02mm and 1.27mm. From CFD analysis, it is established that as the pressure loss of the water jet increases, the outlet velocity of the jet increases. Furthermore, for fruit peeling and cutting process the impact angle of the nozzle should be prioritised as the peeling of the fruit should be smooth and even before cutting the fruit. Thus, the most suitable parameters were found to be 400MPa and 1.02mm of pressure and nozzle diameter respectively. This will allow for the intended fruit cutting process with a stand-off distance that can be ranged from 1mm to 9mm.
