Summary:

This paper first briefly reviews the concept of ejector-driven heating and refrigerating systems. The advantages of these systems over conventional systems are outlined. The issue of momentum mismatch between the primary and secondary flows in ejectors is identified as the primary cause of their inherently low second law efficiency. An idea is proposed to solve this problem by adding a non-volatile liquid to the primary flow to reduce the momentum mismatch. The preliminary feasibility of this technique is explored by developing a simple homogeneous two-phase flow model of an ejector. Preliminary results show that the proposed idea reduces irreversibilities and potentially increases the cooling effect
