Mastering Ejector Design: A Guide to Calculation Methodology and Spreadsheet Implementation

Introduction

Ejectors, also known as jet pumps or eductors, are deceptively simple devices. With no moving parts, they utilize the kinetic energy of a high-pressure motive fluid to entrain and compress a low-pressure suction fluid. While the physics is rooted in basic thermodynamics and fluid dynamics, the design optimization of an ejector is complex.

C. Motive Steam Mass Flow (W_m) – The Critical Formula

Use the empirical Ejector Ratio (R) from standard curves. For a fixed spreadsheet, use this polynomial (for air/steam, single stage):
