Numerical Simulation of Vapor-Liquid Two-Phase Saturated Steam Fluent Flow and Atomizing Jet Cleaning

Abstract

In order to reduce the serious impact of polluting particles on the performance and quality of high-precision machinery and equipment, a cleaning system that uses saturated steam to clean the surface of parts and components is designed to achieve high cleanliness requirements. Based on the standard k-ε model, the large-scale fluid simulation software ANSYS is used to simulate the flow pattern of the steam nozzle to obtain the best distance for steam cleaning. According to the simulation results, a steam cleaning machine was developed and put into an automated cleaning production line to clean three different types of aviation parts. The residual masses of the parts were 0.1 mg, 0.1 mg, and 0.2 mg, and the maximum particle diameters were 549.461 μm, 275.464 μm, and 399.660 μm. The cleaning results show that the saturated steam cleaner can meet the cleaning requirements and get better surface quality parts after cleaning.
