Abstract

This paper presents a mapping of developing adiabatic two-phase R134a flow directly after the expansion valve until the flow is "fully developed" in a 15.3mm inner diameter pipe. Flow characteristics of separation distance, flow type in the homogenous region, void fraction as a function of tube length, and fully developed flow region void fraction and regime were quantified and described.
