Design, Manufacturing and Performance Evaluation of Ejectors Using Experimental and Numerical Methods
Abstract
Ejectors are widely utilized in various industrial systems due to their simple construction and reliability. In this study, the design, manufacturing, and performance analysis of ejectors are examined through both experimental and numerical approaches. A comprehensive theoretical model based on Bernoulli and momentum equations has been developed to predict suction characteristics. The geometry was optimized using flow simulation tools and casting analysis software, with simulations performed in SolidWorks Flow Simulation. Ejectors were manufactured using sand casting techniques and tested under real operational conditions. Comparative assessments of simulated and measured performance demonstrated strong agreement, validating the design process. The results revealed that geometric parameters such as mixing chamber diameter and suction nozzle significantly influence performance. The suction capacity reached up to 103.4 m³/h, more than doubling the original baseline of 52.95 m³/h. These findings confirm that combining simulation, design-of-experiment (DoE), and physical prototyping is an effective strategy for developing high-efficiency ejectors for marine and industrial systems.
