Abstract

This paper studies the possibility of applying the EIT(Electrical Impedance Tomography) technique for investigating the formation and movement of dispersed phase droplets as they stream through a Direct Contact Heat Exchanger(DCHX). In most direct contact liquid-liquid heat exchangers, oil or hydro-carbon with a density different (lighter or heavier) from water is normally used as dispersed working fluid. The main difficulty that arises with arrangement lies in the extraction of performance parameters and visualization of dispersed phase fluids if required. In order to delve into these problems, this paper introduces a number of cases regarding the operation and principle of DCHXs and investigates the possibility of applying the EIT technique whose results are given for several examples.
