Investigations Of Low Pressure Two-Phase Steam-Water Injector

Vapor-liquid injector is a passive device in which thermal energy of vapor is used to compress and heat a cold liquid. In the past such injectors were used extensively for feeding water into boilers, especially of steam engines. Recently an interest in the two-phase injectors revived with new proposals of their application in thermal engineering, refrigeration and air conditioning.
