Steam jet ejectors are critical, low-maintenance components in chemical processing, vacuum distillation, and power generation. They rely on high-pressure motive fluid to compress low-pressure vapor, making their performance highly dependent on precise geometry. Developing an (Excel) spreadsheet is an efficient way to simulate performance, optimize geometry, and calculate essential parameters like entrainment ratio ( ), expansion ratio ( ), and compressor ratios (

A well-structured ejector design XLS typically follows these steps:
